div replace <p> issue

[Carl]

when i edit the content of a div using the div replace option and save the output there is an empty paragraph at the beginning of the text. how do i get rid of this? example:

this is the original text: <div> <p>This is an example</p> </div>

this is the outputted text when i have finished editing <div> <p> </p> <p>This is an example</p> </div>

The <p> </p> appears when i click to edit it. how do i stop this?
