Two render tracks, one of which no longer deletes

It’s a strange phenomenon—my brain’s in a bit of a tangle.

I imported tracks from another Atmos project. Those tracks included a Renderer track (7.1.4). But the Atmos function wasn’t enabled in the new project. When I enabled it, it created a Renderer track, which then became the actual Renderer track. Now, I can’t delete the other one. You can’t see the Renderer tracks in the Edit window (if I’m not mistaken), and it can’t be deleted in the Mixconsole. What should I do? I know it’s not being used and that I could just hide it, but I don’t like that. You should be able to delete a useless track. OR it’s a bug.

Okay, it’s through the audio connections—clear BUS x.x.x. I didn’t get any help, but I’m posting my question and my answer here in case it helps someone someday.
