If you haven’t fixed this problem yet, can you share us the live website link since you said it doesn’t show on the designer? Also, when the live site is different than the designer, that usually means that there is some custom code affecting that, can you confirm whether you’ve got any custom code in the project settings please?
Sure, I believe it has to with the cookie consent. You don’t have to get rid of the template, this simple script should fix this problem with having any side effects. If the problem only persists in the homepage. You can add the script in the homepage custom code before the closing body tag instead of having it in the whole project.
