Hi @Matthew285 and @Lawrene0 ,
In my opinion a filter is a...filter ! It filters something out of a larger amount of results.
So when I filter on listings which have IB, i like to see them. But then the filter suddenly acts like a policeagent: As you are not qualified for IB, we don't show them at all to you ! (BTW I have a verified ID in my profile). I have 5 listings, none of them have IB. Searching Airbnb for my town will show them in the results, but when filtered for IB="on" they don't appear in results. That is correct and it's the way a filter should work.
