Let's give it some time - yesterday it took over half an hour to get self-fixed. Mine is off too:
18176 2013-05-23 19:51:28 2:06:53 17624457 1650 0.00108921 none 237567 25.58627000 90 confirmations left
and earlier when I looked (at around 19:05 server time) my score had just reset and showed almost zero (a few microcoins).
Possibly but its been more than an hour and the # of shares looks normal when its updating the shares usually increases. I also noticed 20 minutes prior to it ending the numbers reset.
