Why the balance is dividing the amount into two reference amounts

We need your help to tell us why some employees are showing two amounts in custom balances with different references to the same balance.

What balance dimension do you recommend using so that the balance only shows a single amount and not the same balance in two amounts with different references or what actions should we do to consolidate the balance into a single result?

This application error is affecting us in custom reports that consult these balances and which are delivered to employees.

Thanks your help
