Vendor Maintenance Balance not matching Aged AP balance

Hi all, I'm currently working to resolve an issue where the balance shown on the vendor maintenance screen is not matching what is seen on the aged ap report. I've checked the documents tab, switched the detailed viewing option from current plus open to all documents and have discovered 6 transactions that were not showing initially and doesn't show on the aged ap report as well. However when I added up all the transactions showing in vendor maintenance, the total I got was what was showing on the aged ap. Is there any way to get the balance to show on the aged ap to show in vendor maintenance.

P.S. the 6 transactions that were found does not have a status of active, is it that the vendor maintenance screen will only show active transactions as well as the aged ap report? I'm still learning the system so any advice and tips would be appreciated.
