It's not just in menu scenes, this also happens in "Kulissen" (i don't know the right english word).
And they doesn't change the position, they didn't even appear.
I have a solution for this, i can make "show all interfaces" and then "hide inventory, hide secondary interfaces, hide [...]" etc.
This works! So i can make all interfaces appear and single ones disappear. It's just gonna be annoying, when there are more interfaces, i'm in the first room and there are already 14 >.<
