Hello,
Please check the information available on https://www.phpdocx.com/en/forum/default/post/7410. If you open a support ticket (https://www.phpdocx.com/support) attaching the template you are using the dev team will check it and they'll generate a custom script to remove/adjust that spacing using your template. Please note that as you are using phpdocx 8.2, a newer release may be needed to accomplish this task.
Regards.
