I just moved up to MacOS Catalina 10.15.4 and I don't know if this is related but now after editing an image in P E Editor, after I click the DONE button, the file appears briefly in its original location in the grid view of Organizer with an orange bans EDITING IN PROGRESS but then the grid view jumps back up to the first images in the folder. This folder contains 800 images. It's a gigantic hassle to get back down to the original image and to continue editing subsequent images. Does anyone have a a solution to this behavior?
