Is this RODI setup correct?

Although it probably came that way from the vendor, there is no need for the GAC "Taste and Odor" filter that is plumbed in after the DI cartridge. After the water leaves the DI stage it is as clean as your system can make it.

Also, contrary to how your vendor originally made the system, a horizontal DI stage is a fundamental configuration error. Remove the DI stage from its clips, and orient it vertically with bottom up flow.

Additionally, we recommend against running the DI out put to a pressurized storage container. Be happy to explain why if needed via PM - not interested in educating the ebay vendors!
