PARTS DO NOT SEE TEMPLATE.PRTPRP

TRYING TO SETUP  SW2020 SP 2.0..  after creating a custom property builder file new parts CAN NOT FIND template.prtprp IN LOCATION "CUSTOM PART FILES" IT ONLY SEES " C:\SOLIDWORKS Data 2020\lang"  and not the "template.prtprp"  How do i get it to see the file in OPTIONS/file locations/custom property files" 

thanks
