When using 'Find duplicates' and selecting 'Specific folder' no results are returned. I have tried with Local and UNC paths.
You can replicate this by creating a new folder, copy the same mp3 twice in to it but use a different file name for one, add it to the library, choose newly created folder in find duplicates - specific folder. No results are found.
OS: Windows 10
Helium Premium build: 12.3.14593.0
This issue has now been resolved.

Issue reproduced, we will test this further.
Thanks for reporting.
Sorry, I was too quick, I will retest.
In the screenshot of Helium you do not have 'Specific folder' selected. Entire Library works fine, but when I select the radio button 'Specific Folder' under 'Find duplicates in' on the right then click search no results come back.
We could unfortunately not reproduce this, tested with Win10, Helium 12.3.14593.
