How do I delete a page I cannot finde? --> Duplicate without user-selected canonical

Hi all,
I’m super stoked to have my website live! BUT, Google is telling me there is a duplicate page to my blog category page. I checked the URLs of every single page I can find in my Webflow Designer interface but I cannot find it, hence dunno how to delete it and make a 301 with that random URL google found that’s not even in my sitemap.
Thanks for your help. I did search here first but everyone just explained how to indicate which page google should recognize as canonical while I want to just find this random duplicate page and remove… :hand_with_index_finger_and_thumb_crossed:

Here is my site Read-Only: LINK

Hi Mathilde, you haven’t shared your site so we can only make wild guesses on how to help you.
My first guess would be that the warning is related to pagination, and that you have a collection list configured for pagination but do not have Webflow’s canonical URL feature setup in site settings (?).

Just guessing.
