Clips with pre-existing, unmoveable envelope control points

Audacity 2.2.1 - Windows 7

Sorry, I couldn’t think of a better title. I clicked on the envelope tool and noticed some of my clips already had a control point at the very end, without me doing anything. I haven’t been able to move any of them. It seems to only happen when my clip ends on a label. There’s no control point at the beginning of a clip that starts on a label. Anyone else seen this?

I was going to edit my original post but…am I just missing the edit button?

I found a control point that appeared without there being a label there.
