Ryoku

The nickname is short, try to put Ukiki. I think it is problem of the sequences FFFF and 0000 but did not appear when you reload it. Pkm Any idea how to fix it?

First let me say that I do not speak English completely. So if you do not understand something I hope will forgive me. Well, the problem is that when I try to put a nickname my pokemon I always mark it as invalid in the Pokécheck. Marco nickname box, use the keyboard and case of there but I always mark it as invalid. What is the correct way to put the nickname? thanks guys.
