Fix the category and tag pages on my wordpress site

Hi,

I use the 'Enhanced Category' plugin to allow me to add pictures and text to category and tag pages on https://rogerspictures.com

Not sure what I've done, but the text/images is also displayed at the bottom of each page as well, which I need fixed.

Also any suggestions on helping to get tag and category pages to rank better in SEO.

Example tag page - https://rogerspictures.com/tag/marquee-wedding-photography/
Example Category page - https://rogerspictures.com/venues/london-wedding-photographer/
