@Albert, if you are logged in, you should see your user id listed at the bottom of the Step 1 form. Do you? (Indeed, there is never an option to select the user id; it only ever pulls from the login session variable.)
It's also possible you got logged out somehow between starting the Step 1 page and submission? (If you are not logged in and you try to navigate to the submission form, it shouldn't populate, instead issuing an error block "You must be signed in...".)
