Strange behaviour of anchored frames inserted at insertion point with distance 0 pt above baseline

[Andersen, Verner Engell VEA]

Hi
I cannot figure out why some of my anchored frames are placed above the
insertion point in stead of at the insertion point.
 
It seems that whenever the frame starts on a page I have this problem.
When I have a sentence above the frame there is no problem.
 
Can you tell me what is causing this behavior?
 
Med venlig hilsen - Best regards
