Flow Simulation Cant find bodies for data import.

Hi guys.  I am trying to run a flow simulation in solidworks.  When I try to import the solid materials from my parts, I get a error message that says.

I understand the one that says not enough data defined and I know how to modify that.  I do not know why it is not importing the other material information after it has already been assigned at the part level.  Any help would be greatly appreciated.  Thanks in advance.
