Production work orders stuck at 86


I have a couple of work orders stuck at 86 that won't advance...variance flag is 1. Compared F3102, F4801, F4801T, and F3112 with a similar work order. No actual units in the F3102 but there are completed units. Any ideas of where else to look for the problem?
FYI- In test when I manually move to 90 I can run manufacturing accounting to close the order. What gives...?
