Using Ternary Operator in Merge Column with Fallback Value: How to Get Clay to Evaluate Next Column

I’d like to use a ternary operator inside a merge column, like in the attached example. If the conditional expression is false, then I’d like Clay to move on to evaluate the following column. I’ve tried passing in '' (as in the attached screenshot), false , null, and undefined as the fallback value to get Clay to move on to the next column, but it won’t. Is there a value I can replace '' in the screenshot with in order to get Clay to move on to evaluating the next column?
