Universal material question

[HHbomb]

Hi,
I just try to use universal material... to make metallic surface
I don't understand why is albedo is inverted vs diffuse : to have full reflection with metallic parameter = 1 I have to set albedo to white, and with glossy material diffuse to black.
I have problems with some PBR textures.
Any clue ?
It is plan to make universal material less confuse in max with some bloks of parameters ? Make parameters in gray when non usable ?
Thanks.
