Multiple flows -- error in token? at top of new flow in part

For some reason the flow heading is misplaced in the third flow of a suite. Correct in full score, incorrect in rhythm section…see three photos here. I have a feeling this is a token issue but I’ve never had to address tokens before

correct in full score

Missing at top of flow in rhythm section:

totally wrong later on in rhythm section:

It’s probably the case that you’ve dragged or altered a frame manually in Engrave mode, in which case you’ve locked in Page Overrides. Remove them and Dorico will put these things back where they’re supposed to be.

It looks as if the wrong type of Page Template has been assigned in each case, a Default template on page 1 and a First template on page nine (except for the page number showing on p. 9).
