That is just how Hughes handles automatic payments, when the bill is generated, they will attempt to bill the card on file on the bill date and not the due date. If you want to get around this, I suggest calling 866-347-3292 and switching to Invoice billing. Yes, there is an additional fee for invoice billing.
I see it's your first post here, so welcome to the community! Charles hit the nail on the head. To add to that, the bill date/due date is most applicable to those on invoice billing. Their bill gets mailed on the bill date, and they have until the due date to mail in their payment. Those on autopay just get charged once the bill date comes around.
