Halcyon Platinum shutter and edge issue

I have a question about the Halcyon Platinum. In the show, there are three rectangular paths, and each path consists of one down light and one face light. (Like picture 1) These paths have been recorded into presets and are used three times within the cue list.

During my daily pre-show check, I’ve noticed that after I adjust the sharp focus and match the shutter angles consistently, they look correct the first one or two times I check them. However, when I go to the next cue that uses the same preset, the focus or shutter position may become slightly different, ending up like in picture 2 and 3.

Since the shutter movement opens from stage right to stage left, and closes from stage right to stage left as well, the focus must be aligned in the stage left / stage right direction, not downstage / upstage.

Is there any way to resolve this?

Thank you so much!
