When linking to a ZOO item my links dont seem to work.

For instance my blog is set to /blog/categories.html
and a post comes up as /blog/17/08/2012/second-post.html

which is great... but when i link to a ZOO Item in my menu its showing up as /our-services/01/01/1970/
As you can see its adding the date wrong, and no title in the URL either?

That should be /our-services/22/08/2012/website-development.html
