Hi Apitchaya,
Since you have already deployed OrgChart application in your NW server, JSPM will not pick the same SCA file unless the application name is renamed, for example OrgChart-<ClientName>.
The application name has to be changed while packaging the SCA, it's not just a simple right click and rename process. I would suggest you to contact Nakisa Support Team (support@nakisa.com) for getting a renamed SCA file.
