In the print module, presets will no longer save the profile (in the color management section). If I select a profile, then control-click on a preset and "update with current settings," the profile field goes blank and the profile is not saved with the preset. Changes in other settings are saved with the preset, so it appears it's only the profile that's not saving.
Things I've tried:
Saving other profiles (Epson and Canson)
Removing all plug-ins and restarting
Resetting the preferences by removing com.adobe.LightroomClassicCC7.plist and restarting
I'm using an iMac and LR 9.4.
3-4 months ago, I upgraded to Catalina, and then about one month ago I did a "nuke and pave," where I erased the HD and reinstalled almost everything from scratch. I'm not sure when this problem started, but it's just been in the last month or two.
Got to the bottom of it after 90 minutes on the phone with a thorough, helpful tecnician who took control of my Mac. Finally resolved the issue when he "reset the printer." I'm not sure how he did that, since online I only find references to resetting the "printing system," and that would ahve required him re-adding all three of my printers (and I don't think he did that). But all's well now.
