[not a] bug with Trumpets in C

Hello,

something strange happens today:
I have setup a score with two Trumpets in C.
In Layout options I have setup under Vertical Spacing „Hide empty staves: After first system“
Now when I delete the music for the second trumpet at some place, the first trumpet gets an instrument change to Tpt in C. Very strange, also as the instrument is in C anyway. I can only avoid the instrument change label by inputting something into the second trumpet. This looks to me like a bug.

I guess you’ve added two trumpets in C to the same player for some reason. Try moving one of the trumpets to its own player.

ah, I understand - will do that…
