Required fields error on model, even when fields are included.

I am attempting to save a skuid model that relates to a Salesforce custom object but I am receiving the error “Required fields missing” for three particular fields. I have updated my model to include those 3 fields, and I am also specifying those 3 fields when I create new rows in the model, but upon saving the model’s changes I still receive the error. Any insight into why this might be failing after I have included the missing fields?
