Cant get document related rule input out of interface

Certified Senior Developer

I have a PM with a non start form interface in it that can acquire a list of documents from the user before going on to the next node of the pm.

All the inputs are set up correctly (saveinto and the form has its inputs set up),  I have confirmed that the value is saving into ri!documents when testing the interface.  

However when it gets to the PM after submitting the user input task, documents is nowhere to be seen.
