After Registration Page, User Stuck on this Option

After the user enters their registration info, it sends them to a page with the following info(below) with no button to move on further. They are inactive also. One reason maybe, I have a "Free Level" that's I can't set to "active". When I try, it says it can't toggle it.

Step 2. Select a subscription

Please select a subscription from the options below.

Also, is there a way I can customize the registration page?

Thanks!
