Basically, every road I try to make, no matter which texture is used, ends up having no color in it like so:

I've tested it on other maps in the editor, and when placing roads they all have color. So I'm really no sure what I am doing wrong. Thus it only occurs on my map Operation Tempest.
Edit: This is not happening in game, but it also means I don't know how the roads will look before I put them together. Very confusing....
