I have been experiencing an issue where the PM6 color filter is not showing all images with that color when I select the option to open folder and subfolders replacing contact sheet. My folder structure includes a base folder with full shoot and selects subfolders. I ingest images into the full shoot subfolder and then move my selections into the selects subfolder which is then imported into Lightroom for editing. I will then use the open folder and subfolders replacing contact sheet option on the base folder so I can see all images in both folders at the same time. I use this option to make additional selections for subsequent edits.
The issue is that many times I don't see all of the images with a color class when I try to filter. It might only show 8 images when there are actually 52 with a color class in the selects folder. If I open the select folder by itself first many times the correct number of images are then shown when I open the base folder and subfolders. When I have experienced this issue I can open the folder and subfolders in PM5 and the image count is correct so this appears to be an issue only with PM6.
I am running the latest build of PM6, build 3889 on macOS Mojave 10.14.6. I am on a 2017 15" MacBook Pro.
I am including screen shots of the issue.
