CSS for non logged in users is different

I am having an issue with css not loading unless user is logged in. For example, on this page – https://www.whatson4kids.com.au/listings/western-australia/wangara/activities-and-classes/high-flyers-trampoline-gymnastics-academy/

There is a button on the right hand side that the text is meant to be white but is still loading as the default Divi color. I have added custom css as follows:

.edit-link gd-claim-link {color:#ffffff !important;}
p.edit-link {color:#ffffff !important;}
a#gd-claim-button.geodir_claim_enable {color: #fff !important;}

I’ve tried adding it to Divi custom css, Divi Booster CSS, and to GD > Design > Scripts. None of these options work.

When logged into WordPress it works fine, but that is obviously not quite right. How do I get the css to render for non-logged in users, who will be the majority of users?

I have attached screenshots for logged in vs non-logged in users.

All other custom css is working fine.
