Amaterasu01

Hello good morning, a while ago I completed all the regions and now I was filling out the pokedex to capture Jirachi, once I completed everything I noticed that I do not have Groudon registered. Then I started the search and noticed that I should have registered it while Hoen's story was happening but that happened and it was not registered in such a way that I cannot capture Jirachi due to the lack of that record. I would like to ask if there is anything that can be done to solve the problem so we can continue moving forward?
