Directory Category Search Field Not Working

WordPress version: 3.8.1
Gravity Forms Directory version: 3.5.4.3

I did this: I created a directory that has several criteria by which the visitor can search including: Company Name, Category, Contact Name, State, Country, and an Open Field. All search fields are working except Category, which is a pull down. I followed the instructions in the FAQ for How do Directory Search filters work? and How do I add a field as a Directory Search filter? But I am still not seeing any results.

I followed all criteria prior to making a new topic including search for this conversation in the forums (http://wordpress.org/support/topic/filter-by-category-3?replies=4). I also downloaded the development version, disabled all other plugins and switched the theme back to default. This issue wasn’t fixed by doing any of those.

I expected the plugin to do this: When a visitor wants to search on category they pull the drop down and select a category. They then hit the search button and should receive a listing of companies that fit the category.

Instead it did this: It shows – This form does not have any entries yet.

Here’s a link to see what I mean: https://infovest21.com/service-provider-directory/
