I am still struggling almost daily with simple formatting issues related to updating old scores I created when I first began using Dorico. I apparently screwed up lots of settings before I understood what master pages were for.
But this, I think is a bug.
1 - Any text objects (shift x) added to the full score appear on the flute part but no others.
2 - it is not reciprocal. text objects added to flute part don’t appear on the full score.
3 - if i delete the (non-system) text object from the flute part, it is deleted in the full-score.
