csn history giving wrong amounts of items sold

Tested with various common items like dirt, stone, mycelium etc, and it seems like a lot of blocks show the wrong amounts when checking history.

When selling 64 stone, the history would say 65. When selling 16 dirt, history would show 13. We've also encountered certain purchases not being displayed at all.

I haven't been able to pinpoint any pattern or cause, as its just happening at random.

Can you please check if those wrong amounts are also in the database.
