Unwanted bars added on opening file

Dorico
1

Each time I launch Dorico 300-500 bars are added to Flows 3 and 9. I delete them, save file, reopen, they are back again.
It might not be related but this happened after detaching a single movie that applied to all flows, and replacing it with three different reels.
Any ideas?

I think we’ll need to see the project itself. Normally the reason for this kind of problem is something like a cue with a crazy duration. Please zip it up and attach it here, or email it to me (d dot spreadbury at steinberg dot de) with details of the problem and I’ll take a look at it.
