Every phpdocx version includes new features and improvements. Previously unsupported features may have been added to newer releases, or past issues may have been corrected.
Sorry, but we don't know what could be wrong. Maybe some extra content/s and style/s are being added by CKEditor? If you send both DOCX (before and after using CKEditor) to contact[at]phpdocx.com the dev team will check them.
