Daring Module Search Logic

I'm trying to figure out how the Dating Module Searches. I only have 3 people who are able to be seen in the search so it makes this easy to test.

1) When you just select "All" from the module search, all 3 users are shown (good)
2) When you just select "Single" or "All" and "Single", just 2 people show.
3) The 1 user that doesn't show (User "jholroyd76") has a relationship status of "Single"

So all 3 users should be show with searches of "All". and searches of "Single"

Thoughts?

The module can be seen at themeparkwatch.com - log in then select the martini glass icon on right-hand side menu.

Thanks.
