Not sure if this has been reported, but version 0.92 of elephant reports some tournament (SNG) finishes as 0. (XP/Titan).
It seems to be more common when elephant is running at the same time and is automatically importing changes made to hand history files, but when it isn't running at the time it appears to be more random (even with a clean database, some of the files imported reported as finished 0th, nothing noticeably different about the raw XML files).
It appears to be making the ROI/$/etc figures/graphs unreliable, possibly because elephant is ignoring the games?
