dynamic text: preStr text appears even when there is no value

I'm using data driven pages (ArcGIS version 10.4), and I want to use dynamic text to create neighbor labels with the text "MATCH LINE SHEET" before the page number. I've used the Insert --> Dynamic Text --> Data Driven Page Name, and put the following in the dialog box:

 

<dyn type="page" property="PageNum_S" preStr="MATCH LINE SHEET "/>. 

 

This gives me "MATCH LINE SHEET 4" when the field "PageNum_S" in the data driven pages index layer has a value of 4 for the page.  However, the text "MATCH LINE SHEET" is showing up even when there is no value in that field for that page (i.e. the map sheet is an edge sheet and there are no adjoining pages in that direction). 

 

According to the Esri online article "Using dynamic text with Data Driven Pages," the text ought to disappear when there is no value:

 

"The preStr and postStr tag attributes let you specify text to add to the start or end of a parsed dynamic tag. These only appear when the corresponding dynamic tag has a value." 

 

Why is my preStr text still appearing, and how can I get it to disappear when there is no value? 

Thanks, Katie
