Cisco 9316D switch port 400G port identified as 800G (2X400G)

[Damon3]

This switch port is 400G, and when we plug in a 400G module, it shows 2X400G-DR4. I would like to ask if there is any command that can make the switch operating system identify whether the current port is 400G or 800G. It seems that this device recognizes this port as an 800G port. The module code shows 400G DR4, so it thinks it is an 800G module with 2 MPO ports. The system version information is as follows (it can be recognized normally in lower system versions)

The Cisco Nexus 9316D-GX Switch (Figure 1) is a 1RU switch that supports 12.8 Tbps of bandwidth and over 4.3 bpps. The switch can be configured to work as 10/25/40/50/100/200/400-Gbps offering flexible options in a compact form factor. Please see feature table below for more information.

The Cisco QSFP-DD800 modules introduce 8x100G and 2x400GGBASE Quad Small Form-Factor Pluggable Double-Density (QSFP-DD) modules, offering customers super-high-density pluggable transceivers along with the flexibility of 400 Gigabit Ethernet and 100 Gigabit Ethernet connectivity options for data centers, high-performance computing networks, enterprise core and distribution layers, and service provider applications. 

You can try to see the module information through "show inventory" and "show interface <interface-name> transceiver details".

I confirmed that my module hardware is 400G, and the normal display should be 400G product model. I don’t know why it is displayed as 2X400G
