Partition 2 not displayed correctly in USETUP

I created 2 partitions with WinXP Home Setup CD, both ~4095 MB in size.
I then formatted partition 1 with WinXP Home, then interrupted XPsetup immediately after formatting.

Now I inserted ReactOS-CD, USETUP shows only the first partition.
The displayed size of the first partition is now correct after bugfix #5156.
Instead of a valid partition (and size) Line 2 shows:
– Type 15 72214 MB

See screenshot.
