Some of the content when clicked on is opening with the whole of the SJ Responsive Content showing again with the page I wanted to open showing at the bottom

why is happening

Dear sir,
Could you please send us your URL link to check this issue.

Thanks.

sorry ive just turn off the popup option now its opening in the same window
now you will see my problem ;0)

The website is being built
shipwreckcharlestown.co.uk/upgrade/index.php

Dear sir,
Do you want to open item details on the same window with this module?
Please send us some photos which you want, we don't understand it, we see your site, but it is normal.

Thanks.

Its just that some articles when clicked on open with the SJ Responsive Content showing above and other articles when clicked on just open without the SJ Responsive Content showing above why does this happen?
