Hello,
You are right, there was a minor bug in the importStyles method. All phpdocx 10 packages (Basic, Advanced and Premium) has been fixed with the correction. If you don't want to download the new package, please edit CreateDocx.php (classes folder in the classic package or Classes/Phpdocx/Create in the namespaces package), and in the importStyles method replace the following line:
$this->_wordStylesT->loadXML($zipStyles->getContent('word/numbering.xml'));
with:
$this->_wordStylesT->loadXML($zipStyles->getContent('word/styles.xml'));
We apologise for any inconvenience caused
Regards.
