Minus zero for successful puzzle

Why is it showing you gained minus zero for successful puzzle in training? I think it should show zero without sign or plus zero when you are successful.

In my case, I get negative points for every daily puzzle, or every first puzzle I solve, and the next puzzle is correct scoring. This has been happening to me for a while now, I think for over 1 month.
