Hidden Error while creating flows layout

I have created a layout for the full score (Whole Flows) which applied the system break very well.
When I create separate flows layout (separate layout for each flow) I cannot find the system break applied correct.
There is a hidden error while creating separate layout for each flow.
Any help please.

It is by design that system breaks don’t carry over to other layouts, not a “hidden error”. You’ll just have to re-input them, knowing that you have the freedom to put them in other places courtesy of the fact that it’s a different layout.

Once you’ve added breaks in one part and formatted it to your liking, you can use Propagate Part Formatting to apply the same formatting to other part layouts.
