Problem in standard workflow of claims in ESS

Hi ,

I am functional consultant and I am facing problem in standard workflow of claims WS18900023 .

When approver clicks on approve button it gives message that ' Validation is succesful 'and it does not get approved.

When approver clicks on Approve button it should say that request has been approved and that workiten should go from his inbox but this is not happening .That workitem still shows in his inbox with same status of to be approved .

Kinldy help in resolving this issue .

Thanks in advance
