Hi Ronnice
I assume you mean the GL control account, not the GL clearing account. The Accounts Payable account in GL is a control account.
There are at least six different reasons this could occur. They range from not having updated your GL (you say you did that), to coding an AP transaction to the GL control account itself, to making a GL entry to the control account that wasn't reversed, to deleting a batch before posting it, to having a date mismatch, to corrupt data.
Needless to say, it would be impossible to troubleshoot this on the forum. It's a service I provide to my clients when they can't figure it out, and I have a feeling your Adagio consultant would provide such a service.
In the meantime, you should search your control account for activity that did NOT come directly from Payables, such as journal entries. It's the most common cause.
