Input should be filtered when user edit values manually from file

[nus-se-bot]

I edit the quantity from files and set it to minus, this is not handled properly when file is reloaded. Perhaps invalid data as such should be discarded, as this affects the functionality for users.

Team's Response

Granted that this is a bug and that we should conduct checks on the data fields when loading them from the saved file. However, I downgraded the severity to low because:

• This is a bug that doesn't occur frequently since normal users will usually not edit their items from the data file itself
• This is a bug that only affects advanced users who choose to edit their items from the data file.

Thus, this bug does not affect most users and does not cause major problems for users.
