[Plugin: Query Wrangler] filtering for meta values

I need help understanding how to use the filters associated with meta values. When I filter for a meta value, do I just enter the value name into the text area? No matter what I enter the filter always comes back reading “Meta Value : none”

The meta keys works by just entering the key name. In my case, “wpcf-status”, so I would assume the value works the same way. The value I am trying to get is for the option “Available”. Do I need to add more than just the value name? Or maybe there is a different value name for the option “Available”, besides just “available” (the keys and values were created using the popular Types plugin, which might use a different naming schema to identify values?).
