You filed this bug against the wrong package. grub-install updates EFI boot variables on its own, it does not use efibootmgr any more.
grub-install registers either grubx64.efi (when installing without shim) or shimx64.efi (when installing with shim), but not both. Also, it deletes superfluous EFI boot variables with the same label as the one being registered ("debian"), so there should not be more than one EFI boot variable with that label.
Can you post the output of "efibootmgr -v" and "ls -lhR /boot/efi/EFI" ?
