Hello I wanted to hack in melmeltal in Pokemon Um so I can transfer it to pokemon shield. So I got the melmetal and it al seemed to be fine when I got the pokémon in home. But now I transferred it to shield. I can use it in battles but not online and when I look at it in the boxes it shows an black pokeball sprite instead of the melmetal sprite. Is there anyway I can solve this? Thanks in advance for your reactions
