J-BusinessDirectory - Category choices

When a user chooses a subcategory jbd returns all listings for the parent category. On the desktop you are given a choice to then reslect your subcategory from the results, but on the phone there is no such option. In either event the users are getting upset because the subcategories are available to be chosen but are not being displayed.

Can you please provide us the steps to reproduce this? We could not reproduce any issues on our servers.
