Tonight I uploaded a folder with a subdirectory. My preference in Transfers:Timestamps has 'Preserve modification date' checked for uploads. All of the files ended up with the same mod time/date as on my system, but both the top-level folder and the enclosed folder ended up with the time/date of the upload.
Probably you need to go back and recondition the mod time/date of folders after you have uploaded all the files into them?
