Bullet levels alignment undone while document is closed

Question

One of my Word documents has the bullets re-aligned after I close it and re-open it. I had a series of bulleted lists in this document that used 3 different indentation levels, like this:

• Bullet level one
  • Bullet level two
    • Bullet level three

When I close the document and come back to it, they have all been re-aligned all the way to the left, like this:

• Bullet level one
• Bullet level two
• Bullet level three

Why is this happening?

Note: I do NOT want a "solution" that requires me to adopt more steps or customize my bullets. I want to understand the root of the problem so that it never happens again, and I want to continue using the regular pre-established bullets that Word documents normally have. A solution that requires me to do more work customizing some advanced settings every time I create a document is not a solution at all.

Answer 1

I'm using Microsoft 365, so just using the autosave function, which appears to be .docx I do sometimes open things in the browser, and sometimes open things in the app (not sure if that matters).

Thanks for the follow-up. Yes, if your documents usually start in the browser, they are almost certainly in the .docx format.

However, editing in the browser version of Word may break multilevel lists, unfortunately, because multilevel number and bullet formats are not fully supported in Word on the web.

Long-term, all multilevel lists should be set up in such a way that each level is associated with a unique paragraph style and only edited in the locally installed full version on a PC (or Mac). See https://shaunakelly.com/word/bullets/controlbullets20072010.html .

Answer 2

The behavior is caused by how Word stores and reinterprets list formatting (indents, tabs, and multilevel structure) when the document is saved and reopened, especially when custom or older-format list settings are involved.

From the provided context, there are two closely related underlying mechanisms:

1. Hanging indents and automatic tab stops for bullets
   Word uses a hanging indent plus a tab stop to position bullet symbols and the following text. In some versions and compatibility modes, Word does not automatically create or honor the tab stop that earlier versions relied on. When the document is saved and reopened, Word recalculates the list layout without those automatic tab stops, which can cause bullets at different levels to collapse toward the left margin and appear as if they are all at the same level. A documented example of this is when a document created or saved in an earlier Word format uses custom tabs for bullets or numbers. In Word 2007 (and later, in compatibility scenarios), the option "Don't use automatic tab stop for hanging indent" can cause misalignment when the file is saved and reopened. The root cause described is:
   • Earlier versions of Word automatically created a tab as part of the hanging indent for bullets/numbers.
   • Word 2007 does not automatically create that tab, so lists that depended on that behavior become misaligned after saving.
   This shows that Word’s internal rules for how bullet indents and tabs are generated and preserved can differ between versions and formats, and those rules are applied again each time the document is opened.
2. Compatibility and layout options affecting existing lists
   When a document is in an older file format or under certain compatibility settings, Word applies a set of layout options that can change how lists are rendered. In the documented case, clearing or setting the "Don't use automatic tab stop for hanging indent" layout option changes whether Word recreates the tab stop that positions the bullet text. If that option is set in a way that conflicts with how the list was originally created (for example, in an earlier version or with custom tabs), the list can look correct while editing, but after saving and reopening, Word re-applies the compatibility/layout rules and the bullets shift. In other words, the root cause is not that the built‑in bullet symbols themselves are unreliable, but that:
   • The document’s format (e.g., older .doc vs. modern .docx) and
   • The compatibility/layout options controlling hanging indents and automatic tab stops determine how Word reconstructs the indent levels when reopening the file. If those settings don’t match how the list was originally created, the visual levels can collapse.

Because Word recalculates list layout on open based on these internal rules, a document that appears correct in one session can reopen with all bullets visually aligned to the left if the underlying indent/tab logic is interpreted differently (for example, due to compatibility mode or the “automatic tab stop for hanging indent” behavior).
