Website Deficiency + Current Staking Rates?

I went to ZKSwap - ZKSwap - Layer-2 for All to find out how I could earn by buying ZKS and staking it. So I clicked on 'Liquidity Mining", which took me to ZKSwap - The ZK-Rollups based layer-2 DEX with the AMM model.. From there, I learned that there are both Proof of Stake Mining & Proof of Gas Mining, both with daily rewards in ZKS. Great so far, except that the yields are currently shown as zero, total value locked in zero, total gas is zero.

Is this just a proof-of-concept that’s not working yet, OR is the defective? Thanks.
