@CalgaryFlame , Thanks for posting in Q&A. From your description, it seems you have created a category in SCUP, but the relevant information could not be found in the SCCM console. If there's any misunderstanding, feel free to let us know.
Based on my experience, Categories you created in SCUP cannot be synced to SCCM console. If you have such a requirement, you may try to feedback to MECM UserVoice to see if we can get this in the future.
