Smartcard bindings

Does anybody know how to remove the smartcard binding created when you import a key? For example, you import a public key using the fetch command in --card-edit this, if this is the first time you do this it will associate your smart card number ("card-no") to the imported key but if you delete this key and use a different smartcard to import the same key you just deleted it will still show the card number of the card you first used.

I'm aware that having the same subkeys in multiples smartcards is not supported by gnupg but is there any way to update this card number association? What can I do to remove the card association when deleting a key? Deleting the whole .gnupg folder works but that's obviously not a proper solution.

Thanks!

   Run
   gpg --list-secret-keys --with-keygrip

   to get the keygrip of your smartcard stubs, then delete

   ~/.gnupg/private-keys-v1.d/.key
