Instrument Names are Gone

Hello,
I can no longer see the instrument names at the start of the page in my new scores. How can I fix that ? I am sure I did not change anything about instrument names etc.
I also did not find an option yet to make them visible again, cause I also did not hide them. The Instrument names (In the Name Editor) are also written out. I´m clueless.

The options are in Setup mode, Layout Options, Staves and Systems, Staff Labels.

I have no idea why I would turn itself off. Unless you have made some intentional changes that you want to keep, do “reset to factory” to restore the defaults.
