Membership register page not making sense

Sorry I need to ask about the default register page on the membership plugin.

When directed there as a test logged in user without access to a level I seem to see another page other than the subscribe options.

I see /register/action=registeruser&subscription=0

Which is a page with a green box saying “Please check the details of your subscription below and click on the relevant button to complete the subscription.”

Then give a table that only says ‘you will pay’

What am I missing here please?
