Events+ and New Shortcodes - Archive & Calendar - Small Rectangles

I am just using one of the new shortcode [eab_archive]

I have customised it so it fits in with the site but I find that I have a small rectanglular box at the top and bottom of the section. I can't work out what it is from looking at the CSS.

You can see it here

I have also tested it with the calendar shortcode [eab_calendar] and it appears to have the same problem.

Can you help?

Thanks!
