Error with Synchronization Project

I have been using the One Identity Manager connector to set up a Synchronisation project with OIM version 8.2. When I simulate or try to run the synchronization I get an error message

Error running synchronization project (Test OIM DB Project)'s workflow (Test OIM DB Project).
Error running synchronization step (Test OIM DB Project) of synchronization configuration (Test OIM DB Project (0cb15dc9-6efd-4a4c-a110-471004a66527)).
Error loading system objects of class CCCNationality (all) (CCCNationality_Master).
The schema type (CCCNationality) does not exist in schema (***************\OneIMProving)!

I can see the schema in the list of target system schema classes and in the mapping configuration.

I have tried a couple of synchronization projects using custom schema as the target system schema and in each case get the same error message.
