Blogger vs WordPress Blog

Hello,

I seem to be having an issue migrating email followers from my old WordPress.com blog (http://gilliantravis.wordpress.com) to my new self-hosted site (http://gilliantravis.co.uk). I have gone through the documentation from JetPack on how to migrate the followers, but when I am asked to "Select WordPress.com Site" I cannot find my old website in the dropdown, although it is a WordPress.com site.

(I am an admin on both sites.)

The blog I need help with is gilliantravistextiles.wordpress.com.
