Profile placer auto sweep breaks after flow

hello everyone. i use rhino7 with mgold3.1. I place a profile placer with autoweep activated so that i can track the sweep shape as i put a new profile on the curve. then i use standart flow along curve to flow the shape. everything looks good and i keep the history so far. but when i edit the profiles and hit enter, that one time edit updates the sweep and the flow but dynamic command profile placer disappears and no matter how i undo it never comes back. i can edit the profiles manually and history updates with the flow but cant add new ones because dynamic command is gone. is this a bug or i do something wrong?

Hi Umut -
This sounds like something you should contact the authors of mgold about?
