This is because the time window inside the system defers the FA to 12-17-2016 12:00AM and the system can't calculate an arrival time window for the FA (it would be from 12-17-2016 12:00AM to 12-17-2016 12:00AM).
The only workaround is to go into the FA (after looking at log files which dispatchers don't have access to) and adding time to the end data. If the schedule manager would just ignore this error and continue on, it would resolve itself when the time window gets extended.
In some instance, this case can be found where the number of registry records doesn't match as shown in the the logs as:
