I am getting duplicate content type error "BizTalk" already exist when creating a site from a saved template template.

I saved a template from a current site, or even from a new site created. It saved successfully.

When i try to create a new site using this template. It gives me error that there is a duplicate content type "Nintex Biz Talk" exist.

It does not create the site.

All out of the box template works fine.

Nintex 2010

SharePoint 2010.
