Lost all my configured watch faces

I just got up and put Apple Watch to my wrist from its charger. Then I found the watch face was changed, now it is the digital activity face, mine was a configured modular face. After unlocking, I find all my configured watch faces are gone. Default watch faces were set.

I tried to power off and power on my watch with no luck.

I upgraded from 2.2 to 3.0 beta3 directly last Tuesday. So today it was just for one week.

All configured watch faces are back. Now I think this thread should be merge here.
