Okey found my problem, and corrected it.
Tip to all, and not to self.
When working with clips/titles and what ever in PPro, you got to keep track of what you are doing.
In this case my problem was that my video files aspect ratio was 1.0 and my titles and sequences was in aspect ratio 1.1 (don't know why, can't remember I chose that), and when I export the move I exported it in an aspect ratio 1.0, that was enough to displace some of the titles.
The solution to this was to create a new project in the correct aspect ratio of 1.0 and then I imported the old project and the I could convert the titles to the correct aspect ratio on opening them.
Too summen it up:
keep those aspect ratios in a tight leash
