Solid coloured texture after SketchUp Export

I have created a simple model in SketchUp and exportet it (Collada .dae format). Importet to Unity everything went fine and looks as it should (after some experimenting with the material shaders) except for 2 textures (see images)

SketchUp (intended) big- Unity small

I checked the material that got imported that Unity uses and their texture is just fine

I tried messing with the tile size of the material but that only changed the colour. (as if only a pixel of the texture is on the material or something like that)

Now i don’t know any further.

I am having the same problem. Only in my case I imported the SketchUp (2015) model directly. same thing, material looks correct in Uniy. Even applied the material to a generic cube for testing. It looks correct on the cube, but the texture is not displaying on the Sketchup imported model. Just a solid color.
