HSDL to mass load ACA fields

I've created a few draft HSDLs attempting to mass load the ACA Eligibility and ACA Full Time fields on the assignment. I am getting a 'Load Successful' result, but am not seeing the fields populated on the assignment. I'm able to go in and manually update the assignment, but we have a few hundred so I was hoping to load. I'm looking for some direction, feedback, or even HDL / HSDL templates maybe someone else has used. Am I missing a process? Thanks in advance!
