Mixer Window (F3) - channel labels missing

There is an issue with the mixer view (F3) in the area under the channels.
The labels etc. are gone…Does not matter what you enabled/disable, there is always blank below the channels

Now after I compared with 9.5 I have noticed that the channel labels are missing :frowning:

Obviously it happens with Projects created with a previous Version of Cubase. The faulty screenshot if of a Project which was made in 9.5.41, then opened with C10 and then saved under new Name from C10. Anyway, all time it is opened in C10 the channel labels etc, are missing in the mixer. Crap.
