can't hide individual tracks inside folder

In one folder in my project, I’m trying to hide some tracks. When I try to change a single track’s visibility, all the tracks in the folder disappear. This doesn’t happen in other folder in the project. Same thing happens if I try the other method of selecting them and hitting “hide selected tracks”.

I tried adding a screen record but am getting a message that the board attachment quota has been reached.

Have you maybe got “Group Editing” (= symbol) activated for that folder? That will make everything disappear if you hide one I think.

Bingo. I didn’t know about that function and must have hit it by accident. That explains some other weird things that were happening too!
