Moset subcategory link to wrong category because of SEF advance

Hi,

I'm using this with mtree and for the most part it works great. However, with SEF advance enabled, one of the subcategories links back to the top level category display.

Please go to www.mauimenusonline.com/joomla/restaurant-directory/west-maui/

And click on the category "Kaanapali" to see what I mean.


Why is the category "Kaanapali" linking back to the main directory??

Any help would be appreciated.

Remove the replacement å=>aa please.

Thanks!
