I’m not sure if that is what you wanted to know. The EUR - GBP - USD slots show the money available on current Payoneer cards you have in different currencies.
Virtual balance is the money you’ve received that is stored within the Payoneer account, and isn’t linked to any of your cards. Currently that money can be withdrawn to your bank account, as it’s not the subject of the current legal dispute.
Their recent FAQ update was to highlight that any payments done in EUR would still go through, they needed to state this as the bank which handles EUR payments is the Wirecard Bank in Germany, which is excluded from the current legal fiasco.
