It looks like you have run the security assist wizard multiple times.
the update page has 3 instances of the Server validation and 3 instances of the update record behavior.
this will happen if you run the wizard multiple times without deleting the pages that where created the first time.
I recommend a fresh start, delete the security assist pages, then run the security assist wizard again to create new copies of the pages and test.
if you still have problems with a fresh copy of the registration page, I'll need to troubleshoot directly, see the private message section.
