Hello,
Thank you for reaching out. It’s possible that WordPress itself may influence the HTML tags, but we understand your concern. To ascertain whether the issue is specific to our plugin, we recommend deactivating our plugin and observing if the problem persists. If the forced use of tags is indeed tied to our plugin, please feel free to reach out to our support team for further assistance.
