Portable flips the part 180° in alignment

This is getting ridiculous, sometimes when running alignments on planes, PC-DMIS flips the part 180°, despite the
fact that all my vectors are correct, theos and whatnots. We have to remeasure the part several times and hope
to hit the correct millisecond PC-DMIS uses to create the alignment correctly...

This is unacceptable and needs to be fixed - is it just me that suffers from this? We are burning daylight because
of the software at this point and not because the parts are incorrect - because we never get to the point where
we can see that...

 It doesn't even work with bestfit alignments as the primary plane used for alignment gets flipped.

If this is a "thing" in PC-DMIS that can't be fixed, please tell me that so I can find another software that works...

Is there anything in the settings editor or the general settings that can cause this behaviour?

EDIT: Pardon my tone, but we have higher-ups whipping our behinds.

This is the measurement and alignment that flips.

    ....Have not noticed this behavior in PolyWorks though. Same arm, same parts, same datums. But to be fair the number of samples is vastly smaller, seems before my coworker and I started no one had even considered using PolyWorks for hard probing. We Googled it, then a few Yolos later its now our standard practice when scanning most parts. If only we had that Mesh license for the Demon, but my boss is dragging his heels. I would kidna prefer to scan most of our stuff with DMIS because you have WAY more control of things, such is life.
