Persistent Customize button badge, no associated recommendations/info

For the past several days, I’ve had the little purple dot in the upper right corner of the Customize button showing in one of my projects. This badge usually seems to indicate some kind of recommendation (in my experience it’s typically an AI suggestion to write a rule around a common practice) but there are no suggestions when I open the menu or any of its submenus. The badge goes away when I open the menu, but returns when I close it again. It’s a little thing, but it’s driving me nuts that there’s a constant peripheral flag for attention that has nothing to say and will not clear.
