Revoke Access not Working

First post and tried to search for answer but found none.

Went to settings to connected apps. Had a number of old ones and hit the revoke access on the right hand side of apps I wanted to remove. The screen “blinked” like it was refreshing but the app connection was never removed. I also went completely out of app and back in just to be sure it didn’t take. What am I doing wrong?

Thanks
