J-BusinessDirectory - How to change the fields that show up in the filter section

I have these front filters but can't see where to change in the back end what fields are used to filter in front end.  

Any advice appreciated 

Here is the screenshot of backend (Post is not allowing 2 photos to be uploaded...)

Go to backend there you have the options ie https://cmsjunkie.com/docs/jbusinessdirectory/businessdiradmin.html#search and I guess you can have a search module where you can customise this as well If I remember right.

thanks for the help
