Hyphen in Arcane Skill Name causes skill to be not recognized.

I'm trying to register a new arcane background (Techno-Wizardry). I can register that just fine, it's just when I indicate the skill roll for that is "Techno-Wizardry" the Powers sheet can't seem to find the skill Techno-Wizardry, even though it's there. I can change registered skill name to "Techno Wizardry" and it works fine once ArcanePropertyManager.registerArcaneConfig is changed appropriately.
