Hi Fanuel,
It was because this option was set incorrectly: https://i.imgur.com/qAcVDr0.png
I have reverted it back to it’s default state. Now I don’t see any results from the un-checked categories.
I also excluded the remaining categories under the ‘Who is’ parent category, as I’m assuming you don’t want any results from them whatsoever – and without exclusions it is actually possible that if no filters match, it could be still match an inclusion: https://i.imgur.com/8o14OWg.png
Currently, it will only match within the choosen subset, and if only each selection strictly matches.
