No Templates showing on Checkout Page

I´m Just installed Prosites and Blogtemplates.
In Prosite in select the checkout page where i created.
Now it looks like this.
I´m Missing the template selection section.
I´m allready setup up two Templates in Blog Templates and on as default. But nothing works on the frontend.
i don´t use grafitiy forms or some others. Just Prosites out of the Box.

I got a licens from NS Cloner with the Addon: Registration Templates. But this word NOT too. Si i deactivated this one.
What is my mistake?

Greetings Harry
