A family of Microsoft word processing software products for creating web, email, and print documents.
I'm having the same problem ever since I moved from 2007 to 2013. It's infuriating! Like you, I work in draft mode most of the time. I cannot fathom why Microsoft made the decision to hide manual page breaks like this.
I found this article which spells out the problem and the solution quite nicely.

Here's my distillation:
There are two problems with manual page breaks in Word 2013.
PROBLEM #1. The paragraph mark
Every time you insert a manual page break, it places that page break in its own paragraph.
As such, the page break indicator does not extend all the way across the screen. If you are in draft mode, and you Show Formatting Symbols, it looks like this:
-----------Page Break------------P
This would be of little concern, if not for the much bigger problem: In draft mode, unless you Show Formatting Symbols, such page breaks are INVISIBLE.
SOLUTION: After inserting the manual page break, make sure you have at least one line of text immediately after the break. Then place the cursor at the beginning of that line, and press the Backspace key. This deletes the paragraph mark at the end of the page break, and it will appear as it has in past versions of Word.
PROBLEM #2. Paragraph formatting
If you insert a page break using the ribbon's Page Layout tab, the paragraph formatting remains unchanged. But if you insert it with the Ctrl-Enter keyboard shortcut, or with the Ribbon's Insert tab, the paragraph spacing is "8pt after", which seems arbitrary, and it really messes up your document.
SOLUTION: Insert page breaks using the ribbon's Page Layout tab.

Fix the paragraph formatting right away (I use the format painter) before it spreads like a weed.
