In the PTR, there's a tag that's incorrectly applied to a file. I tried to remove it, but in the "manage tags" window, there's no tag there to be removed. As a test to see if it was a sibling that I just wasn't noticing, I petitioned every tag to be removed (to see the -1 on the tags) and that tag DIDN'T have a -1 next to it. What's going on here?

If this is some sort of moderation thing by the people who run the PTR and the tag is unremovable for some reason, then is there some way that I can locally override that, and have it be removed on my client specifically? I know that the tag is incorrect, so it's a little annoying that I can't fix it.
