-20000 outflow

I added -20000 as outflow for a transaction and it did not covert it to 20000 inflow automatically. Also it treating the transaction like it was 0 HUF. When I tried to fix it manually and write 20000 to the inflow field, it worked, and inflow became 20000, but the outflow showed still -20000 (treated as if it was 0).
