Deleting photos from Apple Watch

I have been trying to free up space on my Apple Watch to install an update. Under my usage it says 14.1 MB is being used for photos. When I went to “about” under general settings, it said I had 15 photos on my watch. I went under photos in the watch app and selected “none” under synced albums. When I went on my watch and selected the photos app, there are 15 random photos from my “recent” photo album. I have no other albums other than “recent.” I have tried restarting my watch and my phone. After resetting my phone, the watch now has 16 photos in the photos app. I am out of ideas on how to get rid of these photos. Can you help me please? Thank you for your time and help!
