In Starfinder, Soldiers get to pick either Strength or Dexterity, but the 'Feats and Abilities' page's 'Soldier's Key Ability' has a 'Total' of 2 instead of 1. This means you have to select both of them to make PCGen happy that your selections are complete.
I just realized that this is a sources issue and there are separate repositories for that sort of thing. Let me know if you'd rather me move to that and open a separate issue.
