Text Format Changing when Selecting the Complete Word

In Engagements (using Guide) I set up a Dialog with the format I would like to use. I usually clone the Dialog to use on subsequent Dialogs. If I select the text it reverts to the old formatting prior to my custom font/colors. My work around is to Select part of the text, type my new text in and remove the old text. Is there a better way to edit text?
