the WOBP calculator has quite a few bugs in the system. this is probarbly just a bug.
I was pairing male phantom to a female Mojave and the results were a little different.
Using a phantom you get
1/4 normal
1/4 Mojave
1/4 phantom
1/4 purple passion
Using a phantom #2 you get
1/4 normal
1/4 Mojave
1/4 phantom #2
1/4 Mojave phantom #2
