(old) Google Analytics URL showing up in header

Hi,

I’m not sure when this started, I presume since the fore-last theme update.
But my enfold-website is showing the https://www.googletagmanager.com/gtag/js?id=UA-****** url in plain text in the top (with a black bar on the background).

I’m not sure where this comes from. It is not always the case; when I clear my cache then on some pages (Categories) the bar disappears but then it pops up on another page…

When I change the UA-tag in the Enfold options it does not correspond with the UA-tag shown on the website. So I’m suspecting this is an old reference from the early days of using this theme (using it for many years now) but I’m not skilled enough to find out where exactly.

Does anyone have a suggestion ?

Kind regards,
Matt
