Hey there, @robertomelotti. Thanks for coming to the Shopify Community with this question. I hope you're doing well!
I checked out your store and I noticed those grey tags appearing underneath your footer. I noticed that they were also only appearing on your collections and product pages. I decided that I would download a new copy of Brooklyn to my own store to see if I could also generate these tags, and find the setting needed to turn them on/off.
Upon installing the new theme, these tags did not appear for me. Additionally, there are no settings on the product/collection page settings that would turn on such tags. This leads me to believe that the tags on your theme have been added as a result of either a third party application, or custom coding.
The best way to confirm this is for you to download a new version of Brooklyn to your store yourself, and test it to see if the grey tags appear. If they don't, then we can say for certain that the tags are a result of an application/coding, and we can determine the fix from there.
Please, follow up with me when you can once you've had the chance to test out a fresh version of the Brooklyn theme in your store.
