I am running Prepar3d 2.2. I have Orbx global and vector. At stock airports, my runway lights are floating well above the runways. They are lined up as they should be, just well above the runway. Did not have his issues before 2.2

 

The taxiway lights are fine. 

 

Any ideas?

 

Thanks

I should add that by floating I mean above the airplane not just a couple feet above the ground

Do you have other add ons?  You probably have conflicting airport bgls... Could be from an AI traffic addon.  I had the same issue and was able to solve it by rearranging layers in the scenery library.
