Annoying yellow backside texture at heraldic chainmail stuff

[The Hedge Knight]

Hello everyone,

I have a question about the yelllow textures at the backside of heraldic chainmail often used by the mercenary swordsman and caravan guards in floris.
The dds files in the Texture folder in floris seem to be all transparent, and I cant see why the backside should be yellow.

Maybe someone knows how to check out the problem? Many thanks in advance and have a nice day/night!
