Your setup is wrong somehow, the search works, but your URLs and permalinks are not set up correctly.
Here is a search result: https://dentalsave.com/?geodir_search=1&stype=gd_place&s=+&snear=&sgeodir_PracticeName=&sgd_placecategory%5B%5D=&sgeodir_Network%5B%5D=DentalSave+DS&sgeodir_FeeSchedule%5B%5D=&sgeodir_LanguagesSpoken%5B%5D=&sgeo_lat=&sgeo_lon=

If you use it from the correct page, it works fine for me: https://dentalsave.com/dentist-search/

The CSS should be

.entry-title {display: none;}

And sorry to hear about your experience with Divi, there are plenty of GD members that use Divi without any problems.

Thanks

1) After I purchase the multinews theme or another wp compliant code theme, How would i set this up to function with geodirectory.
Just activate the theme you like.

2) How would the Home, listings, detail pages look by default using multinews. Do you have case studies / examples of this?
Cannot find a sample site directly with both multinews and GD.

3) I like the concept of supreme theme. The header with search box in middle & the map next to the listings are my favorite elements. Would i get this by default with the mulitnews theme?
Both those elements are specific to Supreme.

GD is compatible with all WP compliant coded themes.

Page builders do never work with GD pages, only WP pages. It does not matter what theme you use.

That is not the standard tag field, but a multiselect field, and you added specific CSS to that field, see image. I cannot check it because the login details you gave do not have admin privileges.
Thanks

Do you mean the fee your bank charges for the conversion from USD?

GD pages are Listings (Places & Events) & Detail pages & GD Home/Location pages and the GD Search page, the Add Listing page, and the Author page.
Basically all pages that are designed at GD > Design.

GD search shortcode is at https://wpgeodirectory.com/docs/core-shortcodes/#search
