Pure CSS Mega Menu

[the brit]

I am having a issue with my submenu's on my menu - they are showing as standard parent categories on the drop down, rather than either not displaying or opening to right on hover over.

The new master categories is 'Mk3 Sorted - Temp', with the first submenu 'Interior'. As the screenshot should show, the submenu is showing just like the master which is making the drop down long and appearing unsorted.

the site is www.orc hid eu ro .com (without spaces of course )

Thank you!
