What miner unit or model that found this block?
I heard from CK that Bitmain ASIC units give falls report so maybe the cgminer stats you see is falls report

Additionally a lot of hardware (from bitmain) doesn't even report found block correctly, and you may have also been mining some altcoin for your pool and not even found a real bitcoin block but some other bullshit coin.
