As shown below when a different currency is used in the program, the amount by category still remains the same regardless of currency which is not representative of what the feature description describes.

Items for the Tester to Verify

:question: Issue duplicate status

Team chose to mark this issue as a duplicate of another issue (as explained in the Team's response above)

• [x] I disagree

Reason for disagreement: The 'Original' Bug stated here is with regards to the mismatch of the display of list of expenditure by category is being displayed in SGD while the expense was added in CNY, however, the bug I reported was with regards to the list of expenditure by currency being displayed in the wrong currency even when the currency usage for the app is set to a different currency.

## :question: Issue type Team chose [`type.FunctionalityBug`] Originally [`type.FeatureFlaw`] - [x] I disagree **Reason for disagreement:** This remains as a feature flaw as it was sated on the UG that the set currency command sets the currency used by the app without any clarifications on what the limitations of this feature was as shown below. And hence this is a flaw in the feature of the app itself rather than the functionality of the bug as it was shown in the 'Original' bug that the team classified as duplicate that the app does recognizes that the currency has been changed but does not show it when it comes to the list being displayed.

## :question: Issue severity Team chose [`severity.Low`] Originally [`severity.Medium`] - [x] I disagree **Reason for disagreement:** The severity remains to be a medium as when users change the currency of the app say while they are recording expenses while travelling or on exchange, this may result in them not being able to manage their budget properly especially when they attempt to view their budget list by category. This then defeats the purpose and the vision of the app that the team puts forth as shown below in the DG and the User stories. Hence this becomes an occasional inconvenience for most users and therefore the severity level should remain as medium.
