Hello @cd turley
Welcome to the Q&A,
It sounds like you may be accidentally selecting grouped or outlined cells when you enter a formula that references a different cell.
To prevent Excel from automatically grouping or outlining cells when you enter a formula that references cells within them, you can disable the "Outline Symbols" feature. Here's how:
- Click on the "File" tab in the ribbon.
- Click on "Options" in the left-hand menu.
- In the Excel Options dialog box, click on "Advanced" in the left-hand menu.
- In the "Display options for this workbook" section, uncheck the "Show outline symbols if an outline is applied" option.
- Click "OK" to save your changes.
This should prevent Excel from automatically grouping or outlining cells when you enter a formula that references cells within them.
If you still experience the same issue after disabling the "Outline Symbols" feature, you may want to check if there are any macros or add-ins running that may be causing this behavior. You can try disabling any add-ins or macros and see if that resolves the issue.
If this solved your problem, let me know, else provide more information under this Answer.
