Imported object is transparent where it shouldn't be.

I imported an object and it loaded in really weird. See image below...

As you can see, it is obviously there, but the outside is transparent while the inside is opaque. The red and gold objects loaded in just fine, but the blue object is messed up. Here is the material for the blue object...

I looked around a lot but I'm at a loss. I really have no idea where to go from here. Any help is greatly appreciated!
