external subfolder level not processed

[dsm1212]

I have a case where subfolder had subfolders that were not processed. i added the middle subfolder to the list of import paths for the library and they the files were added.

so is like this:

import path is /media/pictures/Andrew

File system has:
/media/pictures/Andrew/2022/fldrA
/media/pictures/Andrew/2022/fldrB
/media/pictures/Andrew/2022/fldrC

fldrC contains: foo.jpg and several other folders fldrD, fldrE.

fldrA, fldrB, fldrC foo.jpg gets added, but nothing from fldrD, flrdrE are processed.

If I add a second import path of: /media/pictures/Andrew/2022/fldrC. Then all files get discovered so permissions seem to be fine. Should multi-level sub folders work? How would I get logging for the discovery to see what is going on?

Two "odd" things maybe: fldrA, fldrB and fldrC are soft links. fldrD and fldrE have spaces and a single quote in the folder name.
