Bug with mega gardevoir quest

[Pikashuu]

Hello, I have encountered an issue while doing the Mega Gardevoir quest.

 

By mistake, I handed in the wrong Ralts. I gave a female Jolly Ralts, which I did not intend to submit. The problem is that, because of its Jolly nature, the NPC seems to have detected it as if I were doing the Mega Gallade quest.

 

However, this makes no sense, since a female Ralts cannot evolve into Gallade under any circumstances. Could you please look into this and fix the issue? Ideally, I would appreciate if the quest could be reset, so I can complete it properly  by getting the Gardevoirite that is the mega stone i want.

 

Thank you for your time and help.
