C4002 sensor is reporting the opposite direction that I am going

I just received the C4002 and I love it already.  I got it incorporated into my Home assistant set up.  

At first it was working great - reporting the proper direction of “away” or "approaching".  Now it reports out the opposite of what is true. 

I might have hit the calibration button, would have have affected it?  If there is something that one needs to do during the "calibration" mode, like walking towards it or away from it, LMK please.

I ordered a few more as I liked how accurate they were for my automations.  So much better than my former PIR sensor based approaches.

I might even try this out on how it sense my dogs to know when they are moving in their den area at night.

Great product, but hopefully I just screwed up something….
