FWIW (& granted these are all tiny files, & only 200K at that)... 07/08/2022 10:56:29 AM Duplicate Cleaner Pro version changed 5.14.0->5.16.0 07/08/2022 10:58:48 AM Scanning - Regular mode- Same content : xxHash-64 - Same file name - Ignore "Copy" part of filename - All file types ...

Did the particular files get deleted (or moved) from outside of DC?

If that is the case, F5, will refresh the Duplicated files list.

The way it looks to me... Up/Down-arrow, moves to previous/next group & changes focus. Ctrl+(Up/Down)-arrow, moves to previous/next group - but does not change focus. Arrow key, left/right moves between images in a group. (Ctrl+Arrow key, left/right looks to do the same, so its' usage isn't even...

Are the files in fact identical, only the file extension may be incorrect? If so, then a (Regular Search) 'Same content' search would find those duplicates. (It would not know the "correct" file extension, only that the files themselves were in fact duplicates.) --- If the files are the sa...

After then scan, you can set your lightroom directory to a "Keep safe" mode.
Then select the duplicated files from your staging directory.

Could you explain that in more detail - with screenshots? I take it these are photos & "system files" (or the like)? Anything "special" (odd) with the file names, lengths, or paths? You're doing a Same Content search? And which hash method? The original folder is renamed to w...

Is your Delete button then intended to (at that point) delete files - based upon existing 'File Removal' settings - without actually bringing up the 'File Removal' tab, so a "just go ahead & do it", kind of thing?

(Without knowing) my first thought is that it would be that it deals with (hash) caching? You might try disabling that & see if you can still duplicate the issue? If it is that, then maybe try disabling hash caching in all except 1 instance? Or leaving hash caching enabled, but use different has...
