This is a rather specialized issue... you probably should be cc'ing the package maintainer as added here.
I have never used this package.. but perhaps the fact that 701 is female yet listed as a father of 801 and 802 could be causing problems. (If so, this may raise issues of family structure flexibility, though it could be appropriate for genetics studies.)
