There may or may not be old saves when you download? idk

I downloaded my game myself from itchio to make sure everythings working alright, and when i loaded up the game it had my saves from when i was play testing. I was confused cause these are completely new files, so idk why that is and if other people can also see the old saves lol like are you supposed to delete that before hitting build distributions? idk idk if you can see my old saves please let me know, but hopefully thats not the case

but if you can then idk. im sure theres some way to delete it?
