Favicon working everywhere except Google search

I’m trying to change the icon for my website on google search. Right now it shows a square version of my logo, however, I’ve changed the favicon to a circle version of my logo. The favicon seems to work on my site, and in some pages of the website on google, but not for my home page preview on google. See attached photos. Is there anything I can do to fix this? I should mention that I changed the icon about a week ago and have since cached my browser, used other computers, etc. The change still does not take affect.


Some info here for you on how Google crawls favicons.
