ok thanksDo you have your Freeshop application updated? Try updating the .cia to the latest (it has an auto-updater in it, if i'm not mistaken).
You can also try updating your title keys in that title key website, but i provide you links because of rules.
To update your title keys, go into the cog button on the freeshop menu > update > click on the qr code button > scan qr code in that title key website.
