How to Fix Missing Undo Edit and Insert Citation Notifications in Word for Mac
Question details
Users receive continuous pop-up notifications stating that 'Undo Edit' or 'Insert Citation' buttons are missing when typing or clicking in the document.

- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Editing a document with third-party macros or citation add-ins (such as Zotero) installed.
- Observed behavior
- Repeated error messages interrupt the workflow each time the user clicks or types, claiming specific buttons are missing from the Word interface.
Ensure you have saved your current documents and completely exited Microsoft Word, as you will need to modify startup folders and restart the application.
Remove Conflicting Add-ins from Word's Startup Folder
Since Word does not natively use these specific buttons, removing the conflicting add-in (like Zotero) from the Startup folder stops the erroneous notifications.
Third-party citation tools like Zotero use macro files (.dotm) that load automatically when Word starts. If these files become corrupted or incompatible after an update, they trigger missing button notifications.
Right-click the Microsoft Word icon in your Mac dock and select 'Quit' to ensure the application is completely closed.
Open Finder. Press Command + Shift + G to open the 'Go to Folder' window. Type in '~/Library/Group Containers/UBF8T346G9.Office/User Content/Startup/Word/' and press Return.
Locate the file named 'Zotero.dotm' (or any other recently installed add-in file). Drag this file to the Trash to remove it from the startup sequence.
Launch Microsoft Word again and open a document. Type and click around to verify that the notifications have stopped.

Isolate the Issue Using Office Safe Mode
Safe Mode allows you to run Word without any add-ins, helping you confirm if a background macro is genuinely the cause of the problem.
Update macOS and Microsoft Office
Running outdated versions of Office or macOS can cause compatibility conflicts with third-party software.
Try WPS Office for an Error-Free Document Experience
If persistent macro and add-in errors in Microsoft Word are slowing down your productivity, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for Mac users without the hassle of complicated add-in conflicts.
- 1. Download WPS Office: Visit the official WPS website and download the free version for Mac.
- 2. Install the Application: Open the downloaded installer package and drag the WPS Office icon into your Applications folder.
- 3. Open Your Documents: Launch WPS Office and directly open your existing .docx files to continue working seamlessly without add-in errors.

Frequently Asked Questions
Why does Word say 'Undo Edit' or 'Insert Citation' is missing?
Microsoft Word does not natively feature buttons with these exact names. These notifications are usually triggered by a malfunctioning third-party macro or citation add-in, such as Zotero, attempting to execute commands that aren't recognized by your current version of Word.
Will removing Zotero from the startup folder delete my saved citations?
No. Removing the 'Zotero.dotm' file from Word's Startup folder only disables the integration toolbar within Microsoft Word. Your actual citation library and research data remain safely stored within the standalone Zotero application.
How do I find out which add-in is causing the error if I don't use Zotero?
You can isolate the problem by starting Word in Safe Mode (hold the Shift key while opening Word). If the errors stop, go to 'Tools' > 'Templates and Add-ins' from the top menu, and disable your add-ins one by one until you find the one causing the notifications.
