I have a multicam sequence in PP 2018. When I want to cut out a certain part and leave the clips untact, I add sequence markers to the timeline and insert it as a nested sequence to my editing sequence. I cut it there and when I'm done I delete the sequence markers on the multicam. As you see on the pic - there are no markers on the lower sequence (multicam). BUT they still remain in my nested sequence on the editing timeline! Worst thing is, that sometimes they do disappear (as they should) and sometimes not. There are no markers anywhere - not in the markers panel, source or program panel.
Is it a bug or is there something I'm not seeing?
