What is not showing up correctly?
I had an issue with quite a few Nexus devices in 11.5.2 not displaying correctly, but this ended up being a view problem. Our 56128's are Machine Type Cisco, but we get all the rest of the information from them, for example:

I opened a case, and had to go into Settings -> Views -> Views by Device Type, and set Cisco to default. For some strange reason the default View for Cisco for us was set to Wireless Controller. Once I set it to default I started seeing the information I was expecting. Not sure if this is what you are experiencing, but thought it might be worth mentioning.
