Incorrect change amount shown after rounding

[navin]

I have rung up an item for R2.97. The total on my slip after rounding is R2.95 but the change shown is R0.03 after tendering R3.00. The change should be R0.05. What am I doing wrong?

Please look at the "DUE" amount & you will note that it shows 2.95 & not 2.97. On the top it shows "Sub-Total" of 2.97 but the "Due" is 2.95......
