EPmaterial can't create a material

Hi everyone, I find myself meeting a problem when using the EPmaterial components.
Seems I can’t create materials correctly for when connect the properties to the components, the output is null.
It may be a very simple problem, but bother me a lot. Thanks for your help!

@WoodyHe For energyplus opaque material,you miss the input of conductivity which must be set. For NoMass material, you miss the input of name.

Below is your model debugged screenshot.
