Incident detected - could not discard it - watch restarted

To me this happened during my last run. I started the activtiy "running" on the Venu 2. During my run I had to jump some steps and the watch suddenly showed the "Incident detection". 
I wanted to discard it by swiping but it did not work. Instead of discarding the watch restarted.

I was surprised but the recording of my run was still ongoing after the restart so I could normally resume my run.

Still it would be interesting if someone else had this? 

False incident detection, Discarding not possible, Watch restarts.
