Hierarchies Not Created in BW for Dimensions

Hello

We have an issue in our Development environment for all of our Dimensions. Hierarchies can be created in BPC but are not being generated in BW follwoing 'save and process'. We discovered the issue when trying to view hierachies in member selection and getting the message " no member description available".

We did not have this issue in our Sandbox environment, but now seeing it for all BPC Environments in our Development installation. Even ENVIRONMENTSHELL dimensions like TIME appear to have hierarchies in BPC structure ( eg PARENTH1 ), but the hierachies in BW are not created.

Any assistance appreciated.
