Pressing enter again should re-apply any of the template data as specified in the sequencer take item (this allows you to change the data and update an on-air item).
Are you using OnOnline scripts to change any of the data in the template? If so, then that probably explains the behavior you are seeing. The OnOnline will only run the very first time the scene goes online; therefore the second time you hit enter, you will get whatever data is specified in the Template Data fields.
