Bug - Watch reset during activity FW 10.10

While running today I paused to change the layout and data as it was my first run. I changed it to six fields, added HR gauge and balance gauge to top and bottom, when I tried to continue my run and it reset as I was backing out to save.

It did this again when I tried to do it while on the move, not paused. I gave up and continued running. 

After my run I noticed that my HR data from the past few hours was gone, so was the training readiness score. Stress data was still there, and when I would drill down into some of the readiness fields, I still see data there but when I back out to the glance view it shows no data. This morning I had a good readiness score. Now it is blank
