Hello and thank you for contacting the Toolset support.
By default, a view will query the posts with the publish status. Maybe the post that you shared in the screenshot "Post.JPG" is not yet published.
If it is not the case, please allow me temporary access to check this view further. Your next reply will be private to let you share credentials safely. ** Make a database backup before sharing credentials. **
I could not find the view that you were working on it, so I created a new private page and I created a new view inside of it. You can see that it returns the expected results here hidden link
The issue with the query filter on your screenshot "Query String.JPG" is that it was using the label of the select field option instead of the value. Check this screenshot, you need to check against the values, on the right hidden link
The following Query Filter hidden link works as expected. It uses "Model Society"(the value) instead of "Model Railway Society"(the label).
