Favicon not showing in searches but does appear in "index" tab of site

When searching for my site on various search engines (chrome, safari, firefox, vivaldi), an image I cannot identify appears next to my company which is not the favicon I added. The favicon I added does appear however once on my actual site in the “index” tab. How can I change the image showing in the search engines? I have cleared cache for both plugin and wordpress which doesn’t seem to help. Any guidance you could give would be much appreciated.
