Watch Face keeps changing...

No, not that the hands are moving...

I set the watch face, then later in the day, it is a different face. I get that something I am doing is swiping it (I guess, but don't see how), but if I leave it on the new face, it new 'accidentally' changes back to the old... Why the heck can't I lock the face I have choses so that it would require an actual input to change it?

It isn't all that professional looking to show off the watch to a colleague who asks to see it, and up comes minnie mouse (or honestly - worse; some fitness tracker that haas started and won't let me out of)
