Filter visibility

Hi!
I’m using your plugin for some time now. Overall it’s great and does exactly what I need, however I have one issue: I use several filters for my product categories and there is one attribute without any products assigned yet. I would like to display it nevertheless (the taxonomy and products will be assigned in the future) in order to maintain an ordered layout on my page instead of having an empty column/space as it is showing now. Is there a setting that will allow me to show attribute filter even if there is no products to be filtered by that attribute?
I have tried all the options in “Values count and output” settings but to no avail.

Thank you in advance!
