Hello,
Template methods don't remove/change existing contents unless it's explicity requested (or using DOCXPath, DOCXCustomizer or other classes that allow changing document contents and styles). As requested in our previous reply, please send to contact[at]phpdocx.com the most simple code and the template that illustrate your issue and we'll check it (we need to run it, so the code can't use external resources such as databases or web services).
Regards.
