Control box actions not saved / synced (10.4.4)

[Alxa 502]

Hi, I have several notes where changes to these control boxes are never saved or synced. 

I mean these boxes:

All changes to the notes involving these boxes are completely ignored and not synced anymore. You edit everything, it says "all changes saved", switch between notes and voilà. next time you open the note, it is as before.
I stopped using these boxes and stick to check boxes instead, they seem to edit, save and sync correctly. Sad, that sync is still buggy and "all changes saved" still means absolutely nothing for real. Anyone else experiencing this problem involving control boxes?
