Empty Folders don't delete!

Hello,

i setup the following:

Files will be synchronised between Server (\\Server\Shared\DocMAX\Music\) and SGS2 (\\192.168.1.120\sdcard1\Music\).
If the same file has been changed on both Server and SGS2 then the newer file will replace the older file.
Files only on Server are copied to SGS2.
Files only on SGS2 are deleted.
If an empty directory is only on Server then the decision is automated.
Empty directories only on SGS2 are deleted.

But after showing this:



It doesn't delete those folders.
Success, no error message!

Any idea?
