GoatBots doesn't recognizes special land

Hey guys, i got the new dragon's tarkir foil mountain (the dragon eye one) and i saw on goatbots website that they're bying for 4,93 tix each.

I created a binder and i'am trying to sell to one of the bots but it tells me that it's just a regular basic mountain and wants to pay me 0.0001 tix.

Am i doing something wrong?
