At least in my Steam/Paid version, the number of kills listed in the line "## monsters perished under her attacks" doesn't not match the number of enemies that you get when sum the number of enemies.

I first noticed when recording individual monster kills in my spreadsheet - though I don't record every monster, the monsters I was tracking summed to more than the monsters listed in that line. After summing the numbers myself, I came to 477, while that line said 428. On my last run, the summed count was 7626 (plus 7 legendary), but the listed number was 7582. On a different run I picked out (with fewer kills, so triple-checking the count is easier), the summed count is 380, but the listed count is 351. Choosing the lowest run on my high score table (for the Steam Version), I sum to 67 kills, with 67 listed. So, certainly the miscount doesn't always happen, but it happens surprisingly early.

Looking back at my older, non-Steam version (3.3.3 - not the oldest I've had, just the oldest installed on this computer), the two that I checked matched their numbers, with 591 and 167 kills each. Given that the discrepancy showed up with so few kills for the Steam version, I was surprised it wasn't there for the run with 591. This would suggest that the discrepancy is newer than 3.3.3 or is isolated to the paid/Steam version only.

I have not tested whether this affect the in-game kill count.
