For the insert the one that you only see a label for is probably the auto incrementing primary key for the table. This is as it should be, if the id column in the table is an auto incrementing primary key then you will not want to insert a value for the id but let the database take care of that for you. If you would like to remove the label you can do so from the design view. You may also have this listed on your update page, if that is the case then you should make sure that you are not setting a value for it there either.
