Joomla Menu Item Alias Doubled Up

Hello,

For some reason the menu item alias being generated is doubling the title.

https://wildernesswatch.org/sigurd-olson-and-the-establishment-of-voyageurs-national-park/sigurd-olson-and-the-establishment-of-voyageurs-national-park

I created a menu of blog posts linking to a single EasyBlog post.

I am using sh404sef and don't have this problem on other pages. I did try resetting sh404sef and clearing all caches and it still generated the double titles.

Why is it doubling the title?

Thanks
