Awesome! This has been bugging me of late! So simple!
I was about to make a new post about this so I'm glad someone else did a while ago. Does anyone know why this happened? I think it happens when I use the Use tool most often but I don't think it's exclusive and it definitely doesn't happen all the time. I also notice that the points on the line do correspond to geometry in my model, but the color is distinct from any other feature in the app. That makes me think it's in some way intentional but I just don't know how I'm causing it to happen.
