Umberto,
Thank you for the link. The Simple Airport Scanner didn't turn up anything glaring in my scan. I ran Scan then searched for KVPS. It didn't turn up any additional airports. On a whim I decided to rename my scenery.cfg file and move it to my desktop for safe keeping.
I then started P3d v4 and let it rebuild a new scenery.cfg file. Low and Behold! All of the elevation issues with KVPS seem to be fixed. I then exited P3d v4, disabled the default jetways via the GSX control panel, restarted P3d, relocated to Gate G1 at KVPS and everything looks great! I selected deboard from the GSX menu, and I'm happy to report no passenger heads poking out the top of jetway.
I really appreciate you taking the time and giving me the tools and knowledge to trouble shoot this problem which was not even a GSX problem in the first place. For that I'm grateful....mark this solved!
