Sleeping in fenix 7

Hello Support and forum guys !

Please inform your programators about problem in sleeping.
If i sleep usualy 8 hour/night and if i aftenoon i sleep 2hour this 2hour sleep overwrites usualy 8hour sleep.
Then all graphs and statistic are bad. Please add (adding up more sleep times) in my saple 8+2=10 hous (no 2h!).
And of course the sum of sleep giving to the day of awakening. If you contact me by email i will send you screenshots.
In Czech Republic we have garmin comunnity at more users have the same problem. Please repair this bug.
As a workaround, you can take off your watch for a shorter second sleep - but we don't want that?
I have last iOS on i11Pro with Garmin fenix 7 Titanium Sollar Sapphire with last FW.
Thanks !  MiK
