Beeping of watch on mtb training, occasily starting flashlight without knowing why

HI, is my watch bugged? when i do mtb training, every now and then it beeps and begins somehow a new lap. I don*t want it to do this. How do i fix this?

The other thing is when i wear the watch occasually the flashlight function activates. Is there a way to deactivate it completly? (thats why i can not wear the watch at work, because the flashlight function always shines in red all over the place)

Cheers
