Battle Harbinger and HeroLab Online

I've tried to make a Battle Harbinger in HeroLab online and it won't let me choose the Battle Creed until I take the Battle Harbinger archetype at 2nd level. I thought the idea was that I could be a Battle Harbinger at 1st level but was required to take the archetype at 2nd.

Who's doing it wrong? Me or HLO?
