Formatting page ends

I have a Musescore file of a composition in several movements, same key but different time signatures. I want to have each movement begin on a new page, which I do with a page break symbol. There are two problems with this:

First, the new time signature appears at the end of the measure before the page break. I understand about courtesy time signatures, but in this case, since the break is followed by a whole new movement with its own title, tempo, etc., I don't want the courtesy time signature at the end of the previous movement. I just want a normal end bar. (I do though want continuous page numbers throughout the score: if the first movement ends on page 7, I want the second movement to begin on page 8.) I can set the courtesy time signature as invisible, but when I save the file and reopen it, they are back! and when I print it, they are there. It seems that the set invisible only makes the courtesy time signatures invisible temporarily on my screen while I'm displaying the file. Is this the way it's supposed to work?

Second, the measure before the page break has segments of incomplete staff lines, even after I set the courtesy time signature as invisible. Again, I just want a normal end measure.

To sum up: what I want is a score with continuous numbers, with page breaks after each movement, but with each movement ending with a standard end measure, just as if it were the only score. Is there a way to do this? Thanks for any advice.
