That is strange, but I cannot check that on my PC by now.

Wings3d works with a manifold surface, so it's a good idea keep it. You can set the height to zero or you can select the top faces and use Extract - I think it will result in a top and bottom object without the side faces (different from the zero thickness I suggested above)
You can set the unwanted faces as a hole or hide them.
