[Plugin: WP Search] wpsearch category specific search not working

Hi,

WPSearch doesn’t seem to work with category specific search as advertised.

site(plugin and category option activated): http://www.kindreviews.com/reviews
go to bottom of page and search “flo”, and select “strains” in the dropdown menu

The search results that come up are from categories not marked with the “Strains”/#142 category

What’s wrong?

Thanks,
zeem
