Category not appearing in Development Goals

Hello,

In HCM Design Studio, I've made "Category" visible/required in the "Development Goal Details - Drill-down" Action. When I try creating a Development Goal though, I'm not seeing the Category field. Does anyone know if this category field for development goals is bugged? It would seem odd that this doesn't work since there's also a lookup called HRG_DEV_GOAL_CATEGORY. Screenshots below:

Thanks,

Nick
