updating games

Recently when I have been updating my games it has been making me have huge updates. For example, I was launching Star Wars Battle Front 2 and it said I needed a 2gb update. I clicked update and all the sudden I was downloading a 69gb update. Its been happening
for a bunch of my other games as well. It's like instead of updating them it just tries to completely reinstall the game. At first, I thought it was because I had an Xbox one x and it was downloading them in the enhanced version or something but when I asked
friends who also had the x they said it didn't do the same thing for them. I have also had other games that seem to download the same update twice. Has anyone else been experiencing these huge updates? Is it just something that the Xbox one x does?

Any help would be appreciated, thanks.
