@dchisholm you might need to update your footprint lib 
The footprint you show is made in a style we really no longer use.
@roboya see Tutorial: How to make a footprint in KiCad 5.1.x (From scratch)? Section Example footprint QFN-64 with exposed pad (Calculate land pattern from part dimensions) for details about how we now do it. Also we have a script https://github.com/pointhi/kicad-footprint-generator/tree/master/scripts/Packages/Package_NoLead__DFN_QFN_LGA_SON Usage is very similar to the gullwing script that has its documentation here https://github.com/pointhi/kicad-footprint-generator/blob/master/scripts/Packages/Package_Gullwing__QFP_SOIC_SO/Readme.md
