Blank space on the first page

Hi guis, I have often a big problem with blank space on the first page. I think, this problem is in scores by import from music xml. The best explanation is in the picture.

. No Make into Frame is not a solution, because it cause a lot of systemm breaks and after them cleaning I have I three pages. I tried to use Staff spacing\Reset Layout and other Reset commands, but any good result. Thx Jiri
