Should throw an error when trying to clear a empty record

Running the command convert-bookmark 1 d/1/1/2000 suggest that date is invalid. In general, dates that follow dd/mm/yyyy but with single digit date/month such as 1/1/2000 are not accepted.

After going into the help tab, I struggled to exit, as the status msg didn't contain anything on exiting the help screen. Similarly, the help section in the UG did not state how to exit the help guide.

Constructors should not be in charge of data validation

The UG claimed that the parameters can come in any order, however running command that involve the INDEX parameter not directly after the command keyword will result in an error.

Entering clear more than twice still clears the records. E,g, entering clear for the third time in a row clears the records. Not sure if this is a bug or the counter was not reset.

According to the UG, the command needs to be entered twice in succession to take effect. But entering the command right after clearing still works.

When converting the bookmark 2, both categories are carried over to the income section. However, in this case, how should i know which module did i receive the income from wihout manually editing the category or title name?

When running the command edit 0 t/hello, a error message that says invalid command format is thrown. However, this should instead be something along the lines of invalid index.

Discrepency in format for DATE which is not put in [ ] but optional.

Inputting a integer that overflows above Integer.max_value results in an error message that for invalid format. Error message claims "Parameters: INDEX (must be a positive integer)" but no range is specified.

The app allows for duplicate records of the same name, amount and date. This design might cause confusion among users.
