I am getting hundreds of shorts when I run Netlist Compare on my Gerbers - however if I import an ODB++ and run Netlist Compare there are NO shorts (on the exact same design) - Why?

Thanks for your question.
Typically when there are so many shorts, etc. - indicates something was incorrectly setup, usually (the drill for Blind/Buried) or wrong layer type assigned.
When I view your sample FAB 3000 workspace file (*.wrk) it has not been setup correctly for Blind/Buried drill. When I import your ODB++ the Blind/Buried drill is correctly assigned -- that's the different between the ODB++ and Gerber -- with Gerber you need to assign layer types, stackup order, drill blind/buried, etc.
Here's some examples how to setup Blind/Buried drills,
