Sorry another question.
We enablet the option “Display results by default when the page loads (auto populate)?”.
But it looks like that the “Ordering” setting doesn’t apply at the first load.
We chose the option “Menu order ascending”.
I added the URL to the test website, if you click on the filter “PROFFIX” and click again you see the order is different.
First order is “publish date” and second is “Menu order ascending”.
