These are not real disklabels, but "faked" up from other information found
on the disk. You can verify with
disklabel -r sd0
which should tell you there is no real label on it.
The kernel generates the fake one usually from the MBR, which you can
view with
fdisk sd0
and I guess there you will see a difference.
Now to fix it you can use fdisk and change the MBR partition type, or you can
write a real disklable to the card and switch the type there. As soon as a
real disklabel is present, the kernel will stop generating fictious ones.
