Silly problem - Help with Core Classes

[Deputy]

So, I assume I've done something silly that's easy to fix, but I can't figure it out. I hope one of you can help.

I'm using HeroLab on my PC for Pathfinder. I'm trying to create a new character who is a Fighter/Wizard. However, those classes are not options for me. They're obviously the basic classes from the Core Rulebook. Am I doing something wrong?

All I see are antipaladin, brawler, cleric, hunter, inquisitor, magus, medium, monk, monk unchained, paladin, psychic, ranger, shadowsworn, and warpriest.

Help!
