Property Test Material ID vs Mat ID

[usc001]

Hello, 
could someone elaborate what is difference between "Material ID" and "Mat ID" Test-Types in Property Test? 
I figured, that the "Mat ID" have the expected behaviour. It checks particle meshes for their Material ID and returns true or false. 
So what does the "Material ID" Test-Type actually do?
Its certainly confusing that they are named (almost) the same but have different behaviours.
thanks in advance

Can you take a screenshot of what you're referring to?

Property Test (in the latest build) does not have a test called "Mat ID".

Hey, yes i attached a screenshot. 
Im not on the latest build though, so by your wording i guess its fixed already. 

Sorry for the post.

Yea, I believe it was renamed.

Material ID reads the material ID override on a particle.

Material ID (shape) reads the material of the first face on a particle’s shape mesh.
