InDesign not recognizing PPD

I'm having an issue where I can't print multiple booklets from a single print job on a 2021 M1 iMac. After checking an older iMac that was able to print correctly, I noticed that certain print settings on the problematic iMac were grayed out and couldn't be changed. These settings include options in the "Setup" section, as well as the "PostScript" and "Data Format" dropdown menus in the "Graphics" section. I suspect this is related to the PPD selection dropdown, which is also grayed out and unchangeable on the problem iMac (this box was editable on the older iMac). I’ve already tried reinstalling the drivers from Xerox’s website, but that hasn’t resolved the issue.
