Yes / No Filter

Good evening.

I'm working with a dataset which contains one column where users can enter either a 'YES' or 'NO' response.  In my dashboard, the customer has requested 2 cards, one counting the number of YES responses and the other counting the number of NO responses, per employee. 

See the below example.  In this instance, the Employee has 6 responses, all 'NO'.  I'm using a 'Count' on each card to return the number of responses, and an advanced filter on each card to show items where the value is either YES or NO.  For this example, because all responses are NO, the YES card returns a (Blank).  Clearly the filter is working correct, however how do I get the (Blank) to display as a 0?

Appreciate any help!
