Mybe check the name of the profile in game.
When i played on stadia
"what is dead and yes i payed twice for this game"
I created a profile with differnt name.
And when i buyed the game from steam i maked different profile name .
In this way it wasn't synced as well.
Oooor mybe you have saves form another pach. I mean technically its possible. To have patch 9 on one machine and patch 8 or whatever on the other one.
