Wrong Wrist HR after 3.30 update

I am using my Fenix 5S for a week now, and today after update I got wrong Wrist HR readings on a Easy run. I tried to walk, reduce pace, and it didn't come back to normal.

I have heard a lot of Wrist HR getting Cadence intease of HR, and I guess that it is what happened on this run.

There's any way to remove this activity from Training Load Status, and effect on VO2, etc? It all decreased a lot.

169 bpm avg, 196 bpm max and 175 avg cadence, 191 max cadence

I doubt my HR peaked at 169.

Now I am supposed to rest for 3.5 days after an easy run.
