Total Outstanding Amount and Current Amount in FDI are retrieving incorrect information.

I am working on an AP analysis in FDI and I am using the fields Total transaction Amount (AP Invoices), Total Outstanding Amount (AP Aging) and Current Amount (AP Aging). However, the values retrieved are not correct. If you see in the image below, I have 5 transactions partially paid, but I am not able to see the Total transaction amount (only in the last one), and in Current amount field the values are showed in zero even when they have an outstanding amount.
Have you ever seen before this behavior? Can someone help me on this?

Thanks,

Maria
