Tried to create a Fighter, but according to the Character Creator, they do not have proficiency in Halberds or Guisarms. Longswords work fine, though. Which is weird, since all those weapons are supposed to be Martial, and Fighters start with an Expert proficiency in Martial weapons.
Fix, please 
Hmm, looks like you’ve caught something very strange! The halberd and guisarme are both coming into the sheet (not just yours!) as if they’ve been manually edited by the sheet user, but that’s definitely not what’s been done to them.
Very odd one, I’ll get it ticketed to the team to take a look, thanks for the catch!
Edit: Looks like there’s something strange going on with two-handed weapons. We’re digging in.
We put out a hot-fix for this issue, your polearm fighter should be ready to wield with both hands!
