Converting to PS file, destination paper size is not selectable

On an IMac running OSX Yosemite, I use Parallels to access Windows 10, printing on an Epson WF 7520. In any application I want to print, Windows converts to a postscript file, and under Paper Handling, Destination Paper Size is Suggested Paper: US legal (grayed out, can't change selection). From my Windows device settings, all printer properties and preferences are "Letter." Printer is fine on Mac side. I have the Acrobat Reader DC subscription and believe it changed a setting somewhere. It was working fine yesterday, and I've spent all day trying to fix this one simple thing! Any help would be appreciated.
