search placeholder/label text not visible

Hi forum, I’m using Wp Job Manager with Divi. I’ve added the jobs shortcode to this page: https://bradfieldassociates.com/jobs/ however there are no labels displaying in the search feilds (eg keywords & location). They diplayed fine in another test site: https://curious-cassowary.w5.wpsandbox.pro (testing wp all import) but for some reason not showing here; which makes very confusing for site visitors. Any help much appreciated.
