Ghost category spam on iOS

I have seen this problem on iOS for some time, but after starting Plex for the first time in a while, it seems the problem has worsened. On iOS I get the same ghosted categories over and over with seemingly no way to remove them. Pressing edit just lets me pin them and you can’t drag to the side to delete either.

I can’t really see where they come from either.

Any idea how to get rid of this mess?

You might have to perform the ‘Reset customization’ procedure on this client:

Whew. Thank you. That solved it.
