When adding page text frames and pictures change position

I have still another problem. When I add a page the text does not flow along, but the textframes simply change position. The same goes with the anchored pictures, which normally go to the inner side instead staying at the outer border.

What can I do (also to keep the picture _always_ near the outer border?

This problem is not new, I have always had it.

Thank you for your patience,
