Cannot change Menu Type back to Mega Menu - defaults to Dropline Menu

Hi - I re-enabled the menu link called Menu Types and selected Dropline Menu and now cannot get the menu type back to Mega Menu - I have gone into Template Manager, selected gk_yourshop and made sure that under the Menu option that Mega Menu is selected. This was all working fine until I selected the Dropline Menu as indicated above. Please help. Website link is:

Hi

While visiting your website, i use mega menu type. This comes from your browser cache.
Anyway, you can always "force" by writing your browser the following url:

You only need to do it once and most probably, your problems will be over.

Cheers

Thankyou Seichinha!
