Vibrate switched off all the time

Hi guys, I've been noticing I was missing calls all the time. Phone is fully silent and no vibration as my watch does that for me. Upon further inspection I noticed that in system/sounds vibrate was switched off (not by me). Now I've been having this daily for the past weeks and tracing back what could be the issue it seems to have started about 1 or 2 beta's ago.

I did a factory set but the problem still exists.

Anybody any ideas cause I'm out of them...
