Frame break makes extra bar

When I have a multibar rest at the end of a flow and select the last barline to make a frame break I get an extra bar on the new page… See example below.

Problem with System (403 KB)

A frame break pushes the following music (in that flow) onto the next frame. Logically, if you select a final barline, there isn’t any “following music” to push into the next Frame, so Dorico has to create some! The solution is to put the frame break on the first beat of the second flow.

Ah, I see! Thanks a lot.
I mean, there is “following music”… The next flow. Starts on same page. But I know what you mean.
