Tier 1 ET stage 1, is a UK address required?

Hello,

I'm applying for a Tech Nation visa. Their website says that I need to apply online to the Home Office and pay the fees there:

However, when I proceed to fill out the form, there is no country selection, and the part where they ask for a postal address insists on a valid UK postal code.

Has anybody else completed their Tier 1 ET stage 1 application online? Is this a glitch or am I missing something?

Thanks!

Update: it was a glitch in their system. I kept trying to enter my address and it wouldn't accept it. I tried again today and it worked! So they've fixed the bug there.
