Coax Datasets (CoaxDataset_A and CoaxDataset_D)

As stated in the High-Level Architecture of the Geodatabase topic, one dataset contains components in a "proposed" or "design" state and is referred to as the "design dataset." The second dataset contains components that are constructed and in the field, representing the "as-built" assets in the final system of record.

Given that all the fields are identical, each feature class is listed only once in these topics. However, in your implementation, the feature class is present in the geodatabase twice, using the naming conventions in the High-Level Architecture of the Geodatabase topic.
