Tables in relationship cannot be seen, "hidden"or away from screen!!!!!

Hi There,
I have some tables in the ERM, cannot see the tables in the Relationship Diagram in Access 2010. They are above the section where all tables are shown, Cannot know how this happened. Any help how I can get them to be shown back in the diagram. I attach a pic.
Thanks a lot.
