I864 cosponsor help

Since being DQ with nvc (mexico), my joint sponsor sponsored his sibling's wife & kids , total of 3 , with i864A (household member) & they have green cards now. I need to update his i864 now that my husbands interview is coming up. My question is, on part 5 question 6 it asks if join sponsor has sponsored new immigrants but it only says i864 or i864ez, no i864a. So do I put 3 on there or leave it blank?
