Brave Element Blocker Is Not Working Properly

For weeks, I’ve been trying to block the annoying and useless sign-in pop-up on IMDB’s website, no matter what, or how I edit it, it always pops up. It’s almost like it has a different code for each site or it’s updated daily. I tried to modify it, but that doesn’t work. I must have it blocked thousands of times, however, I did block the rating element once and it stayed gone. What gives?

Update: The Use App button also won’t stay gone.

Try adding imdb.com##.navbar__coachmark--fadeIn into brave://adblock (custom rules)

To get rid of the login nag

It appears to be working so far. Thank you.
Also, the pop-out window is fixed, before it would only dim the screen.
