If any of the tester logged the same issue twice in the same release then it will considered as a duplicatite bug, this will occured in below scenarios.

-> If a build was tested by 3 members then there may be a chance to log the same issue by more than one tester

-> If a build contains a lot many bugs then there may be a change to log the same issue twice

-> We need to test the build in 3 servers ( Our server, client test server and Product), there may be a chance to log the same issue in any of the 2 servers ( if status of issue was changed to Deffered)
