I can't explain how it got there, but I think that this
Boot/bootx64.efi
is what your system is booting from and it doesn't appear to be being
updated.

I expect that the reason this is present at all is that your BIOS is
bug
gy in the way the extra removable option is intended to workaround,
if
it wasn't you could likely convince your BIOS to boot the
debian/grubx64.efi
by playing with efibootmgr etc but I think you best
bet would be to
set grub2/force_efi_extra_removable=true, try (as root):

echo "grub-efi-amd64 grub2/force_efi_extra_removable boolean true" | de
bconf-set-selections

and then upgrade or reconfigure the package and it should be updated.

Do you have any idea what might have happened at 04:48 on Dec 12?

Ian.
