Tried working SFP from spare chassis and might find the same issue.

Swapped SFP from this device to another device and can be able to see it showing details.

Chassis reboot also did not help.

This CLI display issue could be caused by either software corruption/ hardware error.

So, proceed USB upgrade and check the status once it is completed.

If Junos install media also not help, then replace the midplane.
