Service registry is missing in the namespace

Hello community,

I have a very weird situation that in the name space, when I choose the soap service for a component from Basic Settings->ServiceName dropdown menu, the service registry name is there. However, when I go to HealthShare management->Service Registry, there is not any service showing up. Then I am trying to add this service by clicking the Add Service button and fill out the api information, then I hit save button and it says that "Service with this name and service type already exists", which won't allow me to add this particular service. Does anybody have any insights or thoughts? Thanks so much.
