YADE Ignores First Letter of Directory Names with Recursive Selection

Current Situation

When recursively copying files from a remote server (test.sos-berlin.com) the first letters of the names of the 'first-level' folders that are found will be dropped.
For example, the folders:

 - folder_a
     - folder_b 

Will be copied as:

 - older_a
     - folder_b 

This behaviour happens every time with the configuration provided in the attached settings file but does not happen when a similar configuration is used for transfer from another server.

Log & settings files are attached (use profile_id="ftp:test.sos-berlin.com_2_local_recursive).

Desired Behaviour

Folders generated on the target file system when recursive file transfer is taking place should be correctly named.
