I am adding a second step in my quest to have to "return to npc01". I don't want to use the TaskGroupText because it's just 1 easy thing that has to be accomplished. So I am using What happens then is it displays properly in the quest journal but in the quest helper it display a blank string. If I do then in the quest helper it will display a checkbox with a blank string. What's the proper way to get it to display a single string in the quest journal and a single string + checkbox in the quest helper?

Have you tried putting "I need to return to Deianeira." in both fields?

Yes, that will make it show up correctly in the quest helper but then in the actual journal it will display it twice..once under and indented from the first one. I can't remember if that's how live works or not.
