Merchant Id is not not set in the subscriptions (recurring order)

Hello,

When I create a subscriptions (using addRecurring method of api) I have passed the merchant id but when I check the subscription under a contact in the subscription “Merchant Account” dropdown have not selected the merchant account. Can you please let us know how to remove this bug. this is how I am calling infusionsoft api :-

addRecurring($cid, $allowDup, $progId, $merchId, $ccId, $affId, $daysToCharge)

Thanks
