[Static vs Skeletal Mesh ] A problem importing into Unreal Engine 4

Hi everyone,

Been slowly learning Unreal Engine 4 for quite a while now, and I still do not grasp why I am getting some errors, I recently imported a model into Unreal engine, then made a preview animation of it in Unreal using matinee, when I wanted to expand on it, I imported a second model, which was another I had previously imported as a static mesh to test how it would look, and instead it gives me all sorts of problems with UVWs, my video here explains it, if anyone can help it would be great to get to the bottom of this.

Heres the video

Thanks in advance!
