Materials on Grupp

In the material group “Materials Dual” the material Z-PLA Pro can no longer be selected. Is there a reason for this? Do you have to select it differently because of the Support Material “Premium”? This is the case with Z-Suite version 3.5.0 and Z-Suite Beta version 3.6.0! Can someone help me with what I need to do to be able to print objects with PLA and Support Material Premium?
