Seems like answers are getting lost when old posts are getting ported over.
The answer can be found in the help. For example, in this topic:
http://desktop.arcgis.com/en/arcmap/latest/map/page-layouts/using-dynamic-text-with-data-driven-pages.htm
The brief answer is, when the string is empty, you can tell it to use any user-defined default text (or just make it blank; not sure if it would need a blank space as a sort of place holder or if it can be totally empty) by doing something like this (adjusted for your particular case, of course):
<dyn type="page" property="PageName_NW" emptyStr=""/>
Where's the answer? Maybe I'm blind since they've changed this website format...again. But I don't see it.
Let me know if that doesn't answer your question.
