Sleep gaps on new forerunner 255

Hello, today I woke up to see that there are 2 gaps in my sleep data. The time of sleep should be around 7h40min but its an hour less. The graphs show my watch measured my HR throught the entire night and it spiked to almost 80 where the gaps are, but its not measured as awake, just a gap. The HRV graph has the exact gaps.

  • I have the watch for 2 weeks now, and its the second time that it happened, the rest of the days are on point
    Ive already read all the posts about this but maybe someone found a solution or cause.
