Disabled tabs on product page causing overlap

Excuse the still in progress nature: http://antweightrobots.co.uk/shop/index.php?id_product=2&controller=product

I can't work out how to stop this overlap of the data sheet label up the page cleanly. It was working at one point but after modifying the front page of the site it had changed to no longer be correct.

 

I tried searching for an answer but turned up nothing.

 

Thanks in advance (sorry if the answer is painfully obvious, I'm new to this!).

 

EDIT: I am using a leo theme (hi tech)

any example of how it should looks and works like ?

The line with the datasheet label should look like the 'more info' line and sit underneath the picture in the same way the more info sits under the 'data sheet' section.
