Views Grouped filter returns empty set I am using Drupal 7 and Views 7.x-3.7.

In a view I have an exposed filter "gender".

If I select the filter type as 'single', it works fine. But I want radio buttons rather than dropdown so I select 'grouped filter' option.



Then the filter renders as I like.



But it always returns an empty result set. 

There must be a setting that I am missing. Can you please point me to it?

Thank you.
Well, I could not find a way to make the grouped filter work for me. The solution I found was to use the Better Exposed Filters module. It is quite easy to configure. It worked smoothly for me.
