I would guess that the red is team color and the actual texture has issues.
I don't think this would happen is Import Path is wrong, but it doesn't hurt to double check.
I.E. most often, delete the "wc3Import/" thing for imported textures.
Otherwise the models might has materials setup in a strange way or materials have some details wrong? (DDS format has a few settings that must be correct).
I don't know if the models are confirmed to work so it's hard to know the issue...
