Difficulty with APG Bard Magician archetype ability Expanded Repertoire

[Von Aether]

I'm having difficulty with the Expanded Repertoire class ability of the APG Magician Bard archetype. Expanded Repertoire is supposed to allow the bard to add one spell from any arcane spell list to their spells known.

Expanded Repertoire shows up under Special Abilities, and I can select the spell level, and an additional spell slot of the correct level appears in the spell list, but HeroLab only allows a Bard spell to be chosen, when it should allow any arcan spell.

Is there a workaround for this issue, or am I just doing something wrong?
