I just got my first Windows 11 computer (previously I was using Windows 7). I purchased and installed Start11 v2, which allows me to customize the start menu as well as the taskbar.

I played around with various options. I somehow managed to make it so that a black rectangle is drawn around the program / task item that is in focus. Here's an example: 

But now, I want to remove that black rectangle around the program in focus. Embarrassingly, I can't for the life of me remember how I enabled it in the first place -- I can't seem to (re)find the place in the Start11 v2 options that controls this behavior. (I recall there also being the option to display the taskbar text in a custom color for the program in focus.) Could you please help me?
