removing offlinew sync task

I Run vista Ultima SP1 syncing with a Win Home Server. I am trying to turn of
syncronisation of offline files. They should be a remove tag when right
klicking on the sync task in the manager, but it is not. Help page says it
somtimes is so of some unknown reason.
The only option seems to be right clicking on every synct map to turn it off
(14000) not very tempting as every time i right click and try to remove sync
of a folder a total sync of the 14000 maps starts. Can anyone help me turn
this thing of...!!!!
