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.
Phpdocx doesn't remove not used placeholders. Your script must control them and remove if needed or any other task.
To remove a placeholder just replace it using a blank space.
