Princess Lilligant

Let me start off by saying that I'm brand new to PokéGen. I'm trying to create Pokémon that show up as 100% legal on PokéCheck, but I'm having some issues. For my OT name it says "invalid trash bytes", and for the ability it says it's valid but doesn't match the PID. Everything else looks fine... The only other strange thing is that it says for the nickname "No trash bytes (can have been nicknamed from Cottonee)." I don't know what it means by that. Any help would be greatly appreciated.
