Sleep tracking stops working since Jun 16th

Hello

since Jun 16th my sleep tracking become behave weird.

This is track from Jun 15th, all is fine (sleep&wakeup time are in match), also levels as ussual


On Jun 16th I went to be at about 6am! So the tracking is inaccurate and also levels are missing


On Jun 17th seems like sleep tracking stops working at all. I wen to bed at 7pm and wakeup at 8am. There are no sleep levels and the sleep&wakeup time is as they have been pre-set as my ussual time


I had Fenix 3 and all works like a charm. Unfortunately cant say the same about Fenix 5. I'm becoming very disappointed by them :(
