I was just looking on my account page and the numbers looks weird.
(moved my miners elsewhere when stuff started to go down, hence the low numbers)
EDIT: I guess you just did some recalculations since the 2.5k share is gone but the 0.0000 is still there
Pool does share recalculation ("renormalization") every hour to avoid huge numbers in score. Numbers on profile page are rounded to four decimal place, so if you submitted share a long time ago (before hour or more), renormalized score for worker may be very tiny. This is how score method works; old shares have almost no weight.
