UE5 Material Attribute Layers not appearing as a parameter

Hello,
I’m having a hell of a time using the material layers in UE5.03
I can create the Material Layers and blends but when creating a material and using the Material Attribute Layers node, I can not for the life of me get the nodes parameters to appear either in the detail of the material or in the instance.
As such I cant add any additional layers etc…
Is this a bug or just the usual user error?

Thanks

I guess nobody has ever had this issue.
Looks like my pipeline is stuck for the time been
Any help would be greatly appreciated

same problem here.

for anyone wondering about this. From 5.0 it is still a parameter you just can’t rename it. The layeres are accessible in the tab next to details in the instance.
