About advanced material labels

[sakaki_kaoru]

When applying a label to an advanced material, unintended transparency is represented when in CPU mode.

What I want is the appearance when in GPU mode.
In GPU mode it looks like it is working correctly.

Why does it look different in CPU mode?
I think this is probably a bug.

I will upload a sample file.
I made it with KS9.3 version, but the result is the same with 10.1.
