Duplicate leave request

Hi All,

we are facing the issue as mentioned below, it's only happening in production.

Problem description:

1. Staff applied annual leave on 29.03.2016, submitted the leave. Status is now SENT.

2. Staff amends the leave and changes the date to 30.03.2016 and submitted for approval.

Issue - SWIA and approver inbox shows two items, 1 for 29.03.2016 and another for 30.03.2016.

let me know if you have any ideas on the issue.

thanks,

Isaac
