Material is changing for XFrame, but not for object

Hello there,

So I want to use the Replicator and spawn a bin inside a scene. I will use the Replicator functions to move it to another place and want to give it some material of a list. Well, everything works, the bin XFrame is getting different materials for each scene, but since it has the option “Weaker than descendants” it won’t work. How can I fix this?

EDIT: Okay I now saw that because I imported this bin a lot of subframes have a material. Do I have to delete every material by hand now or is there a possibility in Replicator to set the XFrame that is the highest up as “Stronger than Descendants”?

Thank you very much for your help.
