Naps I took a nap yesterday and my Garmin 7X deleted my previous night's sleep and substituted the nap as "poor sleep".

a long nap substituting for the previous nights sleep on your watch?

Yes. You'll find several threads discussing this if you search the forum.

Thanks for the leads. To me it is a bug not a feature. The watch should not substitute a nap taken during the day for the previous nights sleep and it can't be corrected in Garmin Express or on the watch app. I realize that while you are napping, your body battery is improving and that's enough for me.

My F7 Solar did the same thing this week. Instead of deleting it, I edited the nap to my estimated sleep/wake times from the previous night. To my surprise, it restored all my sleep stages and data.

Thanks, I'll try that. 

I had the same thing happen today. The watch recorded a 1.25 hr nap and substituted it for a 7and a half hour night sleep on my watch. It remained 7:30 on Garmin Connect.

It happened again today. I had a 7.5 hour sleep on my watch this morning and synced it to Garmin connect. I worked on the computer this afternoon and when I was scrolling through the widgets, it showed that I had a poor 1.25 hour nights sleep. the time didn't change in Garmin Connect but my phone app while It shows the correct time slept last night changed the quality to "poor" 16 points. I never had this problem before. I have software version 8.37.
