Site-Wide Tags, Strange Output

Hi guys,
I have loaded the site-wide tags plug-in, and I have the AdSharing Plug-In, the Google ads show correctly on the other pages apart for the site-Wide Tags page where they show twice.

Anyone have any idea of what this might be, any replies in 'for dummies' style please.

Also the text size is large and I cannot see any setup to set the upper and lower sizes for the page, like there is for the widget.

Be gentle'
