they keep turning black before i can train them

looks kinda cool

and I can't seem to do anything to fix the issue. It all started with a 5 days gap 'cause one of the mon died too early and since then has been a struggle. Today has reached 10 days and it makes it hard to have 2 Ultimate Is there a way to fix the problem without starting a new game?...

I met the requirements to digivolve to Ladydevimon and even used to dojo to lock Angewomon, but Meicoomon still digivolves to Angewomon, no matter whether i cross off Angewomon or Ladydevimon. I even used a trainer to get exactly all requirements for Ladydevimon and just low enough to not get Angewomon, but the game just didn't digivolve Meicoomon. I've gotten Ladydevimon before, so I don't know what the problem is....

one of them isnt even using 3 digimon how comes they arent banned?
