It happened to me as well. =]
Debug_Client_Profile_1/2/3 are folders created when you launch the game multiple times. (Like when you want to make a party made out of 4 custom characters.)
Once the party was created and the cinematic was done playing, I didn't realize that I wasn't on the main instance of the game when I closed the 3 others, so my saves ended up in one of the Debug_Client_Profile folder instead of Public.
