Strange positions of player labels when condensing

Any idea what might be going on here?

Hi,
Don’t you have condensing changes at these places?

If so (assuming they’re concerning other instruments), edit them and make sure the French Horns are unticked in the left column.

Could you then upload your file, or just a cutdown version that shows the issue?
(Unless someone guesses what’s going on with just this description, but I don’t!)
