Use Input Controls to filter Saved Search

Hello!

Im using 7.3.2 of Elastic Stack.
I have a Saved Search to filter all my Apache logs with a Filter: event.module: "apache"
I've added this Saved Search to a Dashboard, where I've also an input control that populates a dropdown with host.hostname from filbeat-* index.

However, In the dashboard I get "No results found". If I apply the same filter directly in the saved search there's data shown.

Is it no possible to use input controls to filter through a saved search?

I suspect there's a difference between the output of the input control and the content you'd adding to the filter. Could you share screenshots?
