Models page: filters, sort, and "Add filters" button completely unresponsive

I’m so fed up with all this. Lately, they’ve probably brought in a code agent. That’s the only thing that would explain the recent problems on the site. For example, I’ve started seeing things I shouldn’t (as if I had admin rights, but in reality I don’t). It’s such an unpleasant feeling, to be honest. It could have been fixed in 12 hours. As if no one even comes here anymore.
