Problem with elapsed time

I just completed the results for a multi-day distance race. Multiple fleets, one start. In one fleet of 3 boats, the elapsed time for one of the boats shows as longer than the race (the max time for the race was 3 days, this boat finished in about 2 days 16 hours). SW calculated the elapsed times for the boat finishing before and after this particular boat correctly. I have deleted the entire incorrect boat and re-entered it and I still get this same incorrect calculation.

Does anyone have any further suggestions on what might be causing this one boat issues?

Race is TOD using PHRF ratings individually entered for each boat.

Thanks.
