Hi Edwin,
I’m not able to log-in with the details, so I’m not sure, but I have two possible guesses:
1. Items from the second and third radio are also part of the first (or remaining unselected), therefore it’s treated as an exclusion. On the Frontend search settings -> Advanced panel try changing the Category/Taxonomy terms logic option to “At least one of the selected terms should match” value: https://i.imgur.com/Veo5Tx8.png
2. ..or a category might be excluded into which the expected results belong to as well. You can check that on the Advanced Options -> Exclude results panel.
Best,Ernest Marcinko
