Cookie consent banner does not go away on IE 11 browser

[spano]

Hello, I found out that the cookie consent banner has a strange behavior while using IE 11 Browser.
On the home page, the consent banner will not disappear when you click on the ok button. The consent banner will popup back again and again. This is only on the first page of the site. Once you navigate into the site the problem does not appear. On other browsers look like it is working find.
