Statement Header & Foooter and merge fields for statemen

I tried to add a graphic (our logo) and text to the statement header, as well as a footer with our contact details under the Edit Template function of the Statement report.

Even though I changed the size of the header and footer using the ruler and it appears okay in the Edit Template area, when I run the report it reduces the header area so that not everything shows. The header size on the ruler is big enough but the box containing the header content is much smaller. The same happens with the footer. Can you please tell me how I resolve this?

Also, we are often required by insurance companies to provide the practitioner providing the services in the statement (against each visit). The merge fields provided don’t include this as an option. Can this be added as an option?

Thanks
