Client Context fields not populating in BPM

I am trying to grab the Assembly name field from Client Context in a BPM method directive. I put a message box up to debug and display the values and they are all blank except Company, UserID and Plant. Does anyone know how to get the Assembly name?

What method is this BPM on? Typically the assembly will show without anything special but I know there are a couple circumstances where it will not be populated.

The assembly is on ShipVia and the method is GetList.

Thats what I thought especially when the company and UserID are populated.
