Archeops Error?

[Cabol]

Hey guys, sorry if this is the wrong forum to put this in, but I found an error when making an Archeops set.
I'm trying to use Head Smash, Knock Off (both moves learned via breeding), Taunt (learned via TM), and Stealth Rock (learned via B2W2 move tutor). All moves available via Pokebank, but it says Knock Off isn't compatible with certain moves. Any one know why? Thanks!

In Black and White 2, Archen can only get Head Smash through an egg chain of Relicanth --> Corsola --> Archen. Corsola cannot learn Knock Off at all, and Archen can only get Knock Off via egg (it doesn't get it via tutor). Therefore, the moves are illegal together on an Archen transferred from BW2.

Next time, use Ask a Simple Question, Get a Simple Answer.
