Maybe you created a new template (layout) with the new PDF rather than overwriting the existing PDF with the new changes.
From the plugin’s EXPORT tab, select the correct “Field Map to use:” and verify that the “LAYOUT ID” (layout=”xxx”) is the same layout=”xxx” that is in the shortcode on your formidable form’s “On Submit” box.
Or, send us screenshots of both screens mentioned above for further assistance.
We remain at your service.
