Hi!
I see… but the first 2/4 in my list (as I programmed it) is at bar 23. The first 2/4, shown in your screenshot is at bar 15 then again at bar 23. The next change in my list is at bar 33, but in your screenshot is at bar 25 and so on.
There should be 2/4 only in these bars:
2/4 : Bar: 23 from bar 24 it’s 4/4
2/4 : Bar: 33 from bar 34 it’s 4/4
2/4 : Bar: 44 from bar 45 it’s 4/4
2/4 : Bar: 53 from bar 54 it’s 4/4
2/4 : Bar: 65 from bar 66 it’s 4/4
All other 2/4 were placed by Cubase.
If you check your screenshot there are more 2/4 than the ones I listed here. In my case even If I fix and delete the extra ones, when I open the project again, those signature changes are moved again.
