Foreign Save Files

So I've only started Signalis, been playing for about an hour today, and suddenly there's 2 new save files? (seemingly from the same playthru)

At first I thought it's like, part of the game, but I load them up and it does straight up look like a normal game save with stuff in storage and shit and like?? who made these cuz I downloaded the game yesterday, and these files appeared during my session. I saved a few times before and they were Not There.

Playing on Steam. I don't share my account with anyone.
