You are not deleting the old instances of the rectangle.
Look at the delete method of the canvas widget.
This is Gold Plated Guaranteed  (Tm)  to work.

There is an alternative too, which I have never used,

Look at the coords method of the canvas widget.
It seems to let you get and set the position of 
something.
