Delta Pidgeot Typing Bug

[jeremy]

I'm playing on 1.2.3 and it seems Delta Pidgeot's typing is listed differently from what it is. It is listed as Dragon/Dark, however it is taking super effective damage from Rock and Electric attacks and neutral damage from ice attacks after a roost, implying Dark/Flying typing. EDIT Yet he also takes super effective damage from fighting moves, which would be Dark/Dragon and is not immune to ground. Typing doesn't make sense.
