does anyone know why the retraction points are different here?

problem description:
retractions are set inside (X145/Y150) (home=300/0)
until the section shown in the screenshots, the retraction points are all inside the model, then suddenly they are generated outside. just for 2 or 3 layers.
that happens very often and I never know why.
How great would be to drag retraction points with your mouse where you want them....... *wish*

sorry, my screenshots won't upload, I don't know why. I will post them separately

EDIT: when I change the internal thin wall settings to allow gap fill and set to 0%, the issue almost disappears. single extrusion wall works, too. But still there are some retractions outside..
