The UUID displayed by block info and block detect is different

I wanna mount my NTFS usb by UUID, but when I use block info and block detect, the output is different, why?

Using block info:

/dev/sda1: UUID="0000001800000048" MOUNT="/mnt/usb" TYPE="ntfs"

Using block detect:

config 'mount'
        option  target  '/mnt/sda1'
        option  uuid    '4E56BC2D56BC1823'
        option  enabled '0'

Actually, only lsblk shows correct UUID for me:

# opkg install block-mount losetup lsblk ntfs-3g-utils
...
# dd if=/dev/zero of=ntfs.img bs=10M count=1
...
# mkfs.ntfs -F ntfs.img
...
# losetup /dev/loop1 /root/ntfs.img
# block info /dev/loop1
/dev/loop1: UUID="0000001800000030" TYPE="ntfs"
# block detect | grep -C1 loop1
config 'mount'
        option  target  '/mnt/loop1'
        option  uuid    '0000001800000030'
# lsblk -o name,uuid /dev/loop1
NAME  UUID
loop1 356720BB1AFCCA50

Looks like a bug.
