Shares found stays 0 even when I'm getting payouts
p2pool's `StratumServer status` always displays `Shares found = 0` even though I'm regularly finding shares and getting payouts.

Right now `Your shares position` shows 1 share and I already received 4 payouts during the last 24 hours, yet `Shares found` is 0.

I'm mining within p2pool (not xmrig), version 2.1.

Am I misinterpreting the displayed status values, or is there something wrong?
