Airpod settings only shows disconnected and forget this device

I have an Airpod (2nd Generation)

Model number: A2032, A2031

Wireless Charging Case:Model number: A1938

I can connect on my iPhone .It works perfectly fine, plays music and call supports great even i can charge Airpod case on my wireless charging pad.

But on Bluetooth setting its only shows two option( disconnect and forget this device).

My question are:

*Why it doesn't shows Airpods details on <Settings\General\About> on iPhone.

*Some of my office colleague says its high copy Airpods or fake one, I rechecked the serial number and serial number perfectly matches on apple website.

I have tried to connect on different IOS device and IOS version still have same issue.

Am I only the one having this sorts of problem with my Airpods? I'm bit confused.

Please help..
