Issue with blocking cookies and trackers

Hi, so we've just started using iubenda on our websites. And on a website of one of our clients the compliance report give an error on 'blocking of cookies and trackers' it says 'You are not blocking cookies and trackers until user consent is obtained.' It says this about 'Google Analytics 4' but when i go and check the site manually i can't find the cookie before i choose reject or accept cookies. 

Is this a bug and is it ok to manually edit this error in the report? Or am i missing something?

Kind regard
