2 things first i got pikachu with ash hat using a qr code and i got my greninja ash with  PKSM using the events in that program i got a wondercard for ash greninja and both of them are "ilegal" (pkhex said that both are ilegal.. srry 4 my bad english i understand but i cant write it very well) also i didnt edit them 

that would be all.. thanks! (srry if is nothing just.. kinda worried i want to use them in online and i dont want to be banned.. again XD)

Ash Pikachu friendship issue is likely this, which has been addressed at source and will be fixed in the next release.

For Ash Greninja, make sure Met is Sun/Moon and not Ultra Sun/Ultra Moon. If that still doesn't work, attach .pk7.

Edit: To elaborate further, Ash Greninja can only be sent to SM (see here). Redeeming it on USUM would yield the wrong origin game.
