Is this a Bug? Material OOTB Nodes

So I was trying to do something pretty simple by collecting all the Materials in a project and spitting the data out to Excel.

But for some reason using the following:
Element Types (Material) --> All Elements of Type --> Material.Transparency
gives me an Error relating to an Array. The output appears to be identical to
Material.Name -->Material.ByName but the later is the only one the works.

Is this a bug?

Hit the > and choose @1 and see if that doesn’t fix things.

You’d think they all should work the same but I’ve found that’s not the case.

Nope, that doesn’t work either.

@Matt_Fleming looks like bug from just the screenshot - can you post on the DynamoRevit github issues page?
