Unity keeps saving Scene

My Unity keeps finding a new change each time I click something in 1 of my scenes. I'm using git extensions so i can see what it's changing each time. It seems to be that it is changing a certain value from 0 to 28.5 and it changes it back the next time i click something and it goes back and forth like this forever. This is the exact part it changes:

 --- a/Assets/_Scenes/HUB.unity

It even changes when i don't do anything. While it's not giving any errors, it's getting kind of annoying after a couple of months.
