Instrument name gone when switching order of staves with "Hide empty staves" enabled
1. In the New Score Wizard, add at least two instruments. To one of the instruments, add another staff. Click "Finish."
2. Add one or more notes to the first measure of the instrument with one staff, and to the first measure of the first staff of the instrument with two staves.
3. In the General Style window, check "Hide empty staves" and uncheck "Don't hide empty staves in first system." Click OK.
4. Go to the Instruments list, and switch the order of the two staves belonging to the one instrument.
Result: the instrument name disappears. It's not made invisible. It's not deleted—according to Staff Properties, it should still be there. It's simply gone, and there's no way to recreate it.
This is currently causing me a huge headache because I'm on a deadline. If this could be fixed within the next two hours or so, that would be great.
