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.
