Materials not loading

[Ravewolf 0]

I have cura 4.6.1 and I am using it with a MPSM V2. I have protopasta htpla carbon fiber filament, and I found a material profile for it in the marketplace on cura. I downloaded it, but I can't find it in the materials list, and if I try to import it manually, it comes out as custom material. How do I get this to work correctly? Also I apologize if this is a redundant question, but I had no luck finding any info using search. Thanks in advance!
