Strange anchor moving preview

Not sure if it’s a bug or I am doing something wrong. I have a special _ogonek.e that I also use for the /U
When I try to move the anchor, there is no preview of the movement in the /Uogonek. If I edit /Uogonek, it jumps to the correct edited position, and after that the preview works. Same problem with other characters using this component. Is there a way to make the preview work like with other anchors?
