The red-triangle menu for the top-level TabPage in a Dashboard comes from a script embedded in the Dashboard. The default Dashboard templates create a variable `MainTabPage` to refer to this box (objects visible if you toggle Show Properties):

The template script includes this line:
Try( MainTabPage << Set Scriptable Object( thisApplication ) );
The script is only visible if you toggle off Dashboard Mode. Is there any chance that you either changed the name of the tab page or modified the script?
Edit: changing the title of the Tab Page is fine - it's just the variable name that the script depends on:
