Primes bug in ZP

We have seen this issue in the past (had spoken with James about it) and it has popped up again for the TFC Mad Monday series.

In the two events below, there is a ride in D and a rider in C that show up as having done the sprint prime one extra time than everyone else. It affects all the prime results for the sprint, and since our race series is based on the primes, it really messes everything up. Is anyone else aware of this issue?
