QuiltiX - Houdini - separate3 node - bug?

Hi, I was trying to use QuiltiX to generate some basic mtlx files to use for Houdini. When I saved the file out of QuiltiX, it wouldn't read few nodes in Houdini. I looked at the mtlx file in the editor and noticed that "separate3" was saved as a type "float" but Houdini expected it as type "multioutput". And also the nodes that used outputs of "separate3" namely "absval" and "power" had wrong input-field info. Is this a bug or is this just due to how new all of this is or is it because different DCCs use different naming conventions, although shouldn't they be standardized based on MaterialX spec sheet?

I've attached the files for you to have a look.
