Page Parent/child taxonomy broke

Hi there,

I am using WP3.7.1 with the Associate child theme on the Genesis Framework.

I have a fair amount of pages on my website categorized into a few Main Menu Areas. See the setup HERE. I used to have all the pages relating to for example “Products” on the menu as child pages of a main Products Overview Page. The url would then look something like: http://waterlogics.co.za/product-offering/bottling-plants/. I discovered today that when I click on a menu item relating to a child page, I was redirected to the parent page, although the url was correct in my address bar. It seemed as if the last part of the url was not picked up.
I have subsequently change all pages to have no parent since I cannot have my site not redirecting visitors to the correct page. I did leave one example though, see it HERE. It is supposed to point to a individual product page, but it points to the main product overview page.
I did not make any significant changes to my site.
Please help?
