Restore health and activity data

Earlier today I noticed 5 instances of my Apple Watch in the Health data devices section. I tapped on each one and all but one instance read “device not paired.” I thought that they were no longer useful so I deleted all of the instances that were not paired. Later, I noticed my Apple Watch had stopped counting calories burned. I restarted my watch and when my activity loaded, I had lost all of my data for earlier in the day, plus all of my history. I had earned the “Ring in the New Year” award and was about 400 calories away from the January award.

I reset my iPhone and restored it from a backup created yesterday, but my Health data was not restored to this earlier backup! I tried it a second time but that didn’t work either. All of my prior activity history is missing. Oddly enough, some old awards are still showing although I don’t have any data from the time I got the watch (May 2020).

I tried restoring my Watch from a backup but the only two options were today after the data had been deleted and the day I got it.

I have been searching around for solutions and it seems that this has happened to others. Can someone please help?
