Duplicate Wage Variables

Scenario 1:

Cash advanced was added on 15th July while crew was having another contract. 

Then on 18th July a new contract was added but with a date in the past (4th July) and this caused the duplication.

The extra record can be deleted from crew profile before payroll is closed. 

If payroll is closed there are 2 options: to re-open payroll or to add an Other Earning to balance the deduction.
