Can't change fader page while labelling cues

Thank you for your report. I can see this as well and will start the process of writing it up. I'll update this post as soon as we know more.

This is already written up as

[EOS-53853]
Fader Page cannot be changed while labelling targets

and will be fixed in a future version. I made a note that you're running into this as well.

Thank you for bringing this up again.
