Installed DigiKey Libraries for KiCad5. Browsing available FETs turned up a BUNCH of OOPS. Many of the single JFet symbols have the integral diode illustrated backward (e.g. dk-Transistors-FETs-Mosfets-Single\IRLM6402TRPBF). This should look like the symbol at \IRF954NPBF. This error is rampant so DigiKey should re-check ALL JFET symbols for accuracy.
I would that this should be reported here: https://github.com/digikey/digikey-kicad-library/issues
