Directorist is a pretty solid solution in my opinion, I am not aware of any other one, although I am no expert in this field. The only downside is that filtering by the custom fields is problematic due to the separate fields, but aside from that everything should be okay.
The names issue I assume is likely due to some taxonomy terms being selected to be returned as results. Make sure that nothing is selected here. Those settings are to return the actual taxonomy terms as results, which is likely not something you are looking for.
