Nostalrius Begins - Quality wow vanilla realm (1.12)

My realmist.wtf is this:

set realmlist login.nostalrius.org
set realmname "Nostalrius Begins"

Every time I log in I have to pick my Country and then hit "Suggest Realm" and then it always suggests the PvE realm where my characters are. I click okay and then I'm taken to Character screen.

How come the client doesn't seem to remember that I always pick the same server each time? Is there something I can do with my realmlist.wtf to make it remember and just take me to the character screen automatically?

Thanks,

Change "Nostalrius Begins" to "Nostalrius Begins PvE" and it will default to that server when logging in.
