Egglocke not working as an egglocke

[Former user]

So I decided to play Light version as a female named Rose. The only challenge I'm doing is the Egglocke. I first started having problems when I chose my starter Pokemon. I chose Delta Charmander. It said to swap out the Delta Charmander for a Pokemon Egg. Than it gave me this screen.

So I put Delta Charmander in the box and took it out again. I got Delta Charmander back and it was nicknamed Egg Token but I beat Damien.

So I tried again, playing Light version, 1.1.6, as a boy named Red. I chose Eevee instead of one of the Delta Pokemon. Same problem... I get the 'You cannot interact with this box in an Egglocke' error. Then this happens.

Tried Dark version 1.1.6 instead as a boy named Phantom. Still running into the same error.

You have to swap the Egg Token named pokemon for the egg itself as a trade into the box for the egg.
