I think the missing block is due to special case, where the block was minted after the pool is retired. See some discussions here, https://forum.cardano.org/t/retired-pool-can-still-mint-blocks/110965

I believe due to the missing block the reward accounting is also wrong, but I did not chase it out completely.
