Relogging the next day worked out :)

i select gyarados, and then the following message appears

Same goes for psyduck and goldeen, it wont let me replace another move, just gives me this system message

It wont let me replace other moves but just gives the message that the pokémon learned the move

When i activate the HM. in this case Surf it just says Gyarados learned the move Surf.. it wont let me actually forget a move and replace it for surf? How do i fix this?
