Gnome Shell Extension disables highlight?

Zack here. I have installed a gnome extension: Panel Date Format. I put in my settings and all that, and next thing I know, my clock no longer highlights when I hover over it. It's not anything with my theme, because when I disable the extension, it highlights again. Is there a way to mod the extension to make it highlight on hover again? GNOME version is 40.4. Thanks
