Interactive Template not working

Hi All

I am trying to use table 5064-Interaction Template to attach multiple different files/documents to for each employee in the employee. When i attach a document, it indicates YES, meaning it has been attached. When i go to a new line to attached another different file to the same employee, it replaces the previous attachment. So, it is accepting only one attachment per employee in the employee card.

Is it possible to attach multiple different documents against each employee? What am i not doing right to get many, documents attached for each employee?
