Cannot set "special" ACL's with Windows Explorer

Brief description of the problem


I cannot set any special ACL’s with the Windows Explorer. Normal ACL’s (like Full Access and Read/Execute) are working without any issues.

Detailed step by step instructions to reproduce the problem

  1. Set special permissions

  2. Click on ok

  3. After you click on apply the permissions will revert to “Full control” instead of “special”. If you open the permissions entry again, all check boxes are marked.

Thank you for your help
