Thank you for the reply.
I don’t use the visual tab or toggle between visual and HTML as I did read the same. With this said I work and save while in the HTML tab. It’s strange that they are invisible and you cannot delete them while working in the HTML tab.
If I add <!– –> to add comments, WP will add a </p> tag to the end and sometimes the opening tag. This increases the vertical space between the form elements.
Hopefully there is an answer to this before learning how to use templates.
