Priority Dispatch Report suddenly missing Job/Asm/Op's that were there yesterday

We are having an issue with the priority dispatch report not showing some operations that were there just yesterday. One of our schedules went from 13 pages to 5 in one day which is not because the work was completed. Some operations of the jobs show up but others are gone. I have tried to print the base report also it has the same issue. We have removed one of the jobs that was effected from the schedule and rescheduled but that does not help. Epicor has no idea what happened and has asked for a copy of our database. Anyone have a similar issue that could offer some advice?
