I have a problem with my breadcrumbs that I don't see on other sites using K2.

I have 1 category named "News". When I click on an item in category view, it brings me to the item. My breadcrumbs read: Home | News | News | Article-Name. How do I remove the second "News" in the breadcrumbs? Why are there 2?

Hello cork,

Make sure you have turned cache off for this module.

Duplicate instances and paths can occur if you have a parent menu item called news and a parent category to your item called news as well.
K2 's breadcrumb trail includes parent categories which might not be included in your menu structure as well.
