Hi,
The template you implemented would be a short term fix, that will be lost at every plugin update. Buddypress, Woocommerce and any other plugin which generates a page via custom post type, will need their own template files to integrate with 3rd party themes.
When the issues you are currently experiencing with our plugins are all fixed, allow us to create the template files for you for free. There is very little that you cannot permanently customize with BePro Listings if done the write way. This fix should be done in a child theme, so that it survives updates of your theme and plugins
Note that our recent release 1.0.27 directly addresses the checkbox and dropdown functionality issues you noted. It also addresses the layout issues. As this is a very new plugin, you can anticipate continued refinement of the layout. Are the current usability issues patched from your perspective?
