Additional fields generated by the Wizard

Hello - this post actually contains a series of questions some of which have probably been caused by something I did wrong.
The support I have been using to help get me to this stage are the flash videos from the Introduction to Security Assist. I got over the fact that the videos refer to a different table and worked out that visitors can be substituted for users. I am fairly sure that in following the videos on a step by step basis I was able to set up the wizard however the results were unexpected
1 - in that the userLevel field has ended up on the Vistor Registration and Visitor profile pages. (Two jpegs attached)
2 - in that the log in page has two forms (jpeg attached)
3 - in that the log out page has two forms (jpeg attached)

I am not sure what happened to cause these. I can probably just delete the surplus form code on the login and logout pages but I am not sure how to correct the registration and profile pages.
Should I just delete the lot and start again?
Best wishes
Don
