Hi make sure you are saving on the NAMED save file screen, I made a tutorial on Discord with screenshots to show how to do this as some people are saving two screens too "early" -- it's the right screen if you have to TYPE in a save game name, if you don't have to type in a save name, then hit enter 1 or 2 more times until you get a prompt that says you can type in your save game and THAT's the right spot :)
(End of Episode 7, the screen where you see a mask and it ASKS YOU to type a named save, hope this helps, please let me know if you need any more help!)
