Unfortunately, from your description it does not become clear enough what it is that you try to do. I kindly suggest that you send us a simple page reproducing the issue so we could provide assistance. More detailed explanation on how many docks you create would be appreciated - do you create three docks and add each of them in a different zone? To be able to attach a project, you need to open a support ticket. I am attaching instructions how to do this. Looking forward to your reply.
All the best,
the Telerik team
