How come SMOS ID's the gpu's in wrong order? You know what I mean 0,1,2, etc.

I have a rig built with 7 GTX 1060's. The first 4 installed are Gigabyte GTX 1060 6gb cards starting from first slot. The last 3 installed are Asus Dual GTX 1060 3gb cards. But SMOS ID's them as -

"0" - 6 gb card
"1" - 3 gb card - should be 6 gb card
"2" - 3 gb card - should be 6 gb card
"3" - 6 gb card
"4" - 6 gb card - should be 3 gb card
"5" - 6 gb card - should be 3 gb card
"6" - 3 gb card

Does anyone know this is?

tytanick can you tell me why or help to fix this?
