Hi, artmanjam,
It seems you took it a step further! I didn’t realise it stems from a project started in Cubase 9. I’ll do my next project from a new 9.5 template, and see if the issue persists.
I also experienced the same with “Timecode / Bars+Beats”, and if I use other combinations it’s fine.
I think for me I’m just being careful when saving, switching to Bars+Beats whenever I do so with the keyboard shortcut.
