A guess would be it got a story flag -4 points.

Then something happened that overrode the show score, which is not the same as the real score for stories.

Like you did a edit? (after it got one flag, which would not be seen)

(Random guess)

[Edit] Up votes wouldn't change it until it got back to zero since -3 is not valid.

The external -10 might be too many comments with a low score is not good
