Epson P800: 2 problems printing with LR Classic

Issue 1: paper source popup vanishes. LR Classic, I click print settings, dialog box opens. Click on printer options, then printer settings. The paper source popup, which allows choosing front fine art feeder from P800, has vanished. See screenshots: one shows paper source popup, the other shows it's missing. (This issue ocurred while troubleshooting issue 2; I created a new Mac user, and noticed paper source was missing, so I went back to original Mac user account to take screenshot of dialog box showing paper source, but minutes later paper source popup disappeared.)

Issue 2: My presets don't stick, once I close the print dialog box in LR, and then open it again, it always reverts to premium glossy paper, with high speed and finest detail checked. I've tried creating new presets with different settings, but it always goes back to this. I've tried deleting all presets, and setting preset popup to "default" but the same thing happens. I can select fine art paper, change settings, but once I close dialog box, and right away or later open it again, it's back on prem gloss, with high speed and finest detail checked. I think it reverts immediately: I recently made a matte print that was blotchy, I think it was getting the glossy media settings. And I've been making Epson matte prints with this printer for years, I'm experienced with color management, profile/media settings, etc. 

LR Classic 12.1 MacOS 13.2.1 

Using Epson SC-P800 Series driver, v 12.6.2

I've tried deleting all Epson printers, reinstalling using latest Epson driver. Also, I trashed as many Epson prefs files I could find in Library and user/Library. Restarted printer, restarted Mac. Created new Mac user. Turned wifi off in Epson P800, and made sure I'm not using Airprint in MacOS.
