Smart Narrative: How to hide text when dynamic values can't be calculated

Hi all,

I recently read about the Smart Narrative visual, and I tried implementing it in a dashboard that I'm working on. So far it works fine when there are values to be displayed. However, It's possible that after filtering the values can't be computed, which is not really a problem. But the output being displayed in the Smart Narrative visual is unexpected to me when there aren't any values. 

The behavior that I expected:
- The sentence/text containing the value refferences would not be visible (This is also the behavior of the auto-generated narratives).

Actual behavior:

- It still shows the sentence/text but with no values (see images)

Does anyone know how I can make the text blocks around the values dissapear when it can't compute values?

Any help would be greatly appreciated.

Kind regards,
Carlo
