CMS Blog Collection Auto Added Canonical Tag Issue

I’m encountering a strange behavior of canonical tags in my blog articles:
on each of my article webflow auto added
<link rel="canonical" href=""> tag is present beside of the one I have added in my collection page settings :
<link rel="canonical" href="{{SLUG}}">

Could you please tell me how to disable the auto added one ?

Thank you !
