Multisite content copier goes back to step one.

I select custom post type, click next step.
I enter the blog id and click refresh post types.
It does not find any custom post types so I manually enter the product slug.
It gives me a list of all products so I click select all and add to the list.
When I click to go to the 2nd page of products it takes me back to step one.

Any help with this would be much appreciated
