OPI is missing Attributes from BPMN

I have a BPMN process from NWBPM that I have imported into my Business Scenarion.

In the BPMN there is a dataobject with data about the process.

I want to do reporting based on the parameters found in this process. It could some of the parameters in the process like PayeeType that can be Customer, Vendor or Employee.

I thought that I could see the PayeeType in my attribues in the process, but it is blank.

Is there something else I need to do to import the Attributes like payeetype.
