I believe from what you said, I only want to display the filter values based on the available result. I don't want all possible taxonomy values to show. The issue is that there should be posts attached to the new taxonomy values, but they are showing as having none and so aren't showing in the dropdown.
Is there some code snippet that I can run to force the fetching of posts so the post count is accurate? Or at least run it once so there's at least 1 post attached to each 'media type' taxonomy value.
Hello. Thank you for contacting the Toolset support.
There is no such code available and I'm not sure why the filter is not populating the term even though its assigned to the post.
You may try to resave the permalinks or your taxonomy term or even post and check if that help and you able to see the term with filter where post is assigend.
