I had 2 problems that started yesterday after I used HDR merge. When LR created the DNG file, it did not show up in the folder (although I could find it in All Photos). Since then, when I export any files (not from the HDR process) to another folder and synchronize them, it goes through and completes the process, but then it shows no files in the Previous Import or in the destination folder. However, if I close LR, then reopen it, in both cases of the HDR DNG file and the Exported File show up in their respective destination folders. In the case of the exported file, the Previous Import now shows the correct number of files that I had exported before closing LR. I am using LR Classic 2020 and MS Windows 10 as my operating system.
