Obviously it’s pretty easy to edit the staff labels, but I can’t figure out how to edit them and remove the auto-numbering. Also, I haven’t quite figured out what causes the auto-numbering to engage as there doesn’t really seem to be a pattern in the current file I’m working on.
Here’s what it currently looks like:

I’m not entirely sure why sometimes the auto numbering is a 1, sometimes 2, sometimes appears (Tbn. 2), and sometimes doesn’t (Tbn. 3), but I’d just like to either turn them off or manually override them with a custom staff label. Is there a checkbox somewhere I’m missing? Simply renaming the staff doesn’t usually make the auto-number go away, but sometimes it does like for Tbn. 3. Obviously I just want the systems to be setup with the full instrument name on the top system and then descending numerically. Any advice?
