OPC imported costs different from GC P6 schedule

Our GC has $30M of costs in their P6 schedule. When we import into OPC we see a total of $8M. GC does not have any expense costs. We send .xer file to another scheduler and they see $30M in their P6.

Any clues why OPC is not importing the $30M? We have not seen this before with other GC P6 schedules.

Thanks!
