A Tally ledger can't be viewed in voucher

A user is experiencing an issue in Tally 9 where a specific ledger, 'TDS-Professional-Receivable-2019-20', is not appearing in sales vouchers. The ledger is correctly structured under a detailed hierarchy of groups and sub-groups. While basic amounts and GST are visible, the TDS ledger is not. Suggestions include checking F12 settings and exploring potential hierarchy issues, as moving the ledger higher in the group structure might resolve the problem.
