Pre-created strength training alters the weight lifted by subtracting .5 pounds frequently and I have to fix it after every set

Hello! For the last several months my Fenix 7 subtracts .5 pounds from many of the strength weights I prepopulate, as well as leaves the last lifted weight in there when I start a predetermined body weight exercise. Is there a way to fix this so I don't have to manually bump every set back up to what I had it set at in the watch for the workout? For instance, if I set a weight that I will lift as 20 pounds, it shows 19.5 when I'm done and I have to bump it back up to 20. I would love to not have to do this. I've created different workouts, and sadly they all do this. This started in the fall, I believe. 

Thank you!
