Normally, the UTM Settings entered in the first step (Information) should appear in "Creatives" step after the creatives are created by clicking on the "Add New Creative" button.
However, if you chose the creatives from the library or added the UTM Settings after adding the creatives, the settings won't appear in Creatives. So you need to either re-enter the parameters in Creatives step or add new creatives after adding the necessary parameters in "Information".
