Changing order of fields in Drupal's content type

I am using Drigg on Drupal 6.17. Drigg has a content type called as "Scoop". I try to change the labels and order of fields. Normally, this is done in Content Management > Content Types > Manage Fields . But some fields that are shown in Create Content screen are not shown in Manage Fields screen.

The screenshot of Manage Fields is here:

The screenshot of Create Content view is here:

The first three fields (Submit the scoop as.., Scoop's URL, Scoop) in Create Content form are not shown in Manage Fields view.

I would like to ask the reason for this. They must be defined somewhere else. Where is it?

Manage fields is for editing CCK fields that you have added. Other fields from different modules often have a weight setting that you can change to move the field up and down, which you would get to from the main content type editing page.
