Additional context

The main issue regarding this bug is the stems and beaming within the synchronization between the main score and parts. The synchronization settings flick on (specifically the stems and beams) when the user tries to implement something different from the main score. This can also be seen across different layers and gets super confusing when having a rest in the main score and just the cue notes in the part.

At the end of the day though, this issue is arduous to deal with in regard to cueing. You would have to manually highlight certain elements to hide them on the main score.
