Help R36s

Hey all! Please help me.Im idiot.🙈😭I don't know what I did wrong, I didn't get to it and this one is not mine! (my bfs consol) But instead of the 10-15 thousand games it used to have, it only says 6 thousand or not even that much. It's all messed up. I don't know where the other games are. A lot of the games we played this morning disappeared. Please help me, what could I have done wrong or how can I fix it! Thank you
