The modal that appears in the storefront doesn't resemble the one in the Preview
When I open my site, this modal comes up but I can't understand how to remove it since I have configured another one in the Geolocation section?

Answer: The popup you mentioned appears to belong to Shopify's Geolocation app. Please assist in updating its settings to disable the popup.
Refer to this article for more details, or you can contact Shopify support for more details.
