There are currently 2 moderators who have a total vote count of less than 0 during the primary phase. But the total vote count sticks at -1 and is no lower than that. Neal, for example, currently stands at +97/-140 which should give a total vote count of -43.
I remember having seen this during the last elections as well, but I assumed it to be just a bug and I didn't find it important enough to report on meta. But right now, after many elections using the same engine, not only on Stack Overflow, this issue seem still to manifest.
Can we please fix it? Or is this working as designed?
