I checked and it's still not updated, I can verify it through your site's source code. And the page in your screenshot is broken which means it's not really updated. It happens when you updated cornerstone first before the theme.
I recommend deactivating and deleting your cornerstone first, then update your theme. Then go back to the validation page and let it re-install the cornerstone.
And please deactivate your caches too after the update, your cache is overkill. I see two in your screenshots which function just the same and having too much also cause issues.
