Is anyone else having a glitch with the time tracker?

So for some reason when I play a game on the steam deck that I already have played on my pc before it changes the time to show I lower time, like I had 90 hours of playing megabonk but when I started playing it on the steam deck it changed my time played to 50 hours and it's been doing it to other games. Is anyone else having this glitch, and should I be worried about it?
