All those models are for X-Plane 10 therefore they aren't fully compatible with X-Plane 11. In X-Plane 11 there were changes in how reflection and many other things are treated. So you should wait to 3rd party authors to update their models. Look, if you try the standard Cessna 172SP it looks great. It's not Laminars fault you're using a model that isn't designed for the current (BETA) release.
Good luck, and more readings.. :)
