When I edit a menu item and save it the phrase "k2-categories" gets added to the URL, right before the alias. The menu items URL looks good when adding it but it's when I edit the item "k2-categories" gets added.
The URLs that are edited looks like this: www.mydomain.com/k2-categories/alias. In the menu item options k2-categories is no where to be seen. This happen to all my menu items that I edit, not only the k2 ones.
Any idea how to remove it?
