$20 jackpot Sit and go ticket

I recieved a ticket for $20 sit and go from a deposit bonus, but when i enter any $20 sit and go it deducts the money from my cash total, instead of using the voucher. Not a huge deal but i would think there should be a way to use the voucher instead of cash, or by default use free vouchers before deducting from the cash total.

Welcome to the Forum! Can you confirm when you received this ticket?
