I think I need to apologise to Ren because brought me to other side :')
Anyway, how to return the main menu to the original one?
Either start a brand new game or continue playing until you reach the end of the demo. I suggest starting a new game, as it unlocks some new features!
But if you don't want to do all that, there is also a setting in the "data management" screen that will return the game back to normal.
Thanks a lot for the info :)
