title: Content control toolkit creates extra custom xml parts on reopen docx
body: <p>I am creating a docx with 2 rich text controls and 1 picture control. I open content control toolkit, create 1 custom xml part, type in the xml and bind xml tags to the content controls. I save the mapping and close it. When I reopen the docx, I see 3 custom xml parts created. All 3 with all the content controls. I am surprised why it would do that. As a result, when I apply the bindings using docx4j API, the data gets updated in the last custom xml part. Guess the output docx only shows the first custom xml part and hence I dont see any bound values. When I unzipped the docx and looked at the contents, I see that the last cutom xml part has been updated with the values, I set using the docx4j code. Am I doing anything different that makes content control toolkit create the extra custom xml parts? Please let me know.</p>
