Title-Tag is set for the “close-function x” on cookie-banner

Hi there,
latest SEO-screening discovered two title-tags on my site, which can affect negatively to SEO. I found out, that the complianz cookie-banner has a cross on the right top to close the banner. That cross appears in HTML page source as <title>close</title>, what is not nice for SEO, because every page of my website has two title tags through this.
Would be nice if you could take away that title tag with the next update.
