Adding budget via the add transaction feature in project costing

Good Day,

I pray that all is well.  Our user added project budget for 3 periods.  All 3 periods were posted to commitment control but only 2 posted to project resource.  The PC distribution is not distributed for 1 of the periods. When navigating to the "Add Transactions" under project costing, the transactions are there but when clicking on the "Process Transactions" the transactions are not selected to be processed.  What flags should be reset for the transactions to be selected?

Thanks,
