Hello,
Maybe the symbol you are using to wrap placeholders is being used in other contents of the DOCX, so the existing placeholders can't be returned correctly. We recommend using a symbol that is not used in other contents of the documents to wrap placeholders: setTemplateSymbol. Since phpdocx 11, ${ } can also be used to wrap placeholders too: ${VAR}
Please send to contact[at]phpdocx.com the template and the username or email of the user that purchased the license you are using.
Regards.
