Can't pick Witch in HLO

[Weatherman]

I feel I must be missing something obvious, so hopefully someone here can help. I'm trying to create a Witch, but it's not available on the list of classes in HLO. I own the Advanced players guide, so I should have access to the content. What am I doing wrong?

Have you activated (turned on) APG in Hero Config? If that's not it, raise a bug report from within HLO.
