Those locked rewards are earned; they are yours no matter what even if you hit “claim” you will see this balance of “Can Unlock Rewards” and this is across all participating pools.
As an example as of 2nd January 2022, 15 days had passed after start lock block (17th Jan). the full period is 6 months.
When users claim, then 20% treats will be claimed directly. Also, when users run unlock on etherscan, he could get 15days/6months * tokens from total locked amount. We are working on a UI solution for this.
