Blog Filter using tags listing tags that have no content

First off, thank you guys for the amazing plugin! It is great, really. I’m facing an issue that might be an oversight when filtering data from the database but, let me explain: I’m working on a site with multiple content categories and wish to filter each content type based on its tags, so imagine I have two categories: “Media” and “Cases”, both have independent tags, ok? When I filter the content based on a given category, “Cases”, I expect that the filter should only show tags that are present on posts of that category, but it is showing all tags regardless if there is content on it or not.

I’ll try to illustrate it further:
Post 1 – Category: Cases – Tags: Success, Law
Post 2 – Category: Media – Tags: TV, Interview

If I use the Blog widget and “Categories Filter Rule” as “Match Category”, select the “Cases” category and further down on “Advanced Settings” choose “Get Tabs from” and select “Tags”, the page will show the filter for the blog widget with all tags [“Success”,”Law”,”TV”,”Interview”], but if I select “TV”, it will be empty, as there are no posts under the “Cases” category that have “TV” as a tag.

I hope I made my case clear, and that’s really the only issue I found, I hope you’ll be able to help me fix my setup or point me to a proper solution. Thanks again for the amazing plugin.
