Total balance and withdrawable balance is different

Hello, I wanna withhdraw my tokens, but there is a difference between total and withdrawable balance. Why is that so and what should I do to withdraw all of the tokens?

Thank you

Hello Treeleaf. Some of your tokens are staking rewards which are locked for 12 months, starting from the day you received them.
