Bandwidth shaper on winbox not working on some clients:HELP

Some of my clients traffic more than what bandwidth they are shaped on on the WinBox. By this they use up more bandwidth than they were limited at. What could be the problem? and how can this problem that wants to cripple my network get fixed. Pls someone should help me! :frowning: It is not happening to all the clients rather a few :confused:
