Question. I noticed some of the blocks coming in are under 12.5 btc. I thought a block was automatically 12.5 plus any fees. Am i missing something? Thanks
I think you might be confusing miner reward with block reward. The former should be 99.1% of the latter, and it can be lower than 12.5 after 0.9% pool fee is subtracted.
IntroVert is correct. You're looking at the "Rewards" page, and the "Miner Reward" listed is the block reward minus the pool fee. The Block Reward is shown on the Blocks page.
