PureRAW6 images not showing up in Lightroom Classic Library Folders

I recently installed PureRAW6 on my Mac Studio, and use it with Lightroom Classic. I shoot Sony. I think I’m using the latest release of all programs. When I process images using Plug-in Extras, I can find the resulting .dng files in Finder. The images also show up in the DxO PureRAW 6 Collection. They don’t show up in the Lightroom Library folder, however. When I try to copy/import the .dng files from Finder, or from the Collection folder into the Library folder, I get a message that the files already exist in that folder and can’t complete the copying. But I don’t see them there. I don’t have any filters on that would not show .dng files. How can I get the PureRAW 6 .dng files into my Library folder with the original ,ARW files?
