Port Bandwidth Usage (in gbps) 20
As updated by engineering, the license counts only the interfaces which have advance feature configured.
Hence not all the available interfaces are counted & which is why only lesser value is shown in output.
We can conform which all interfaces are using advance feature using "show system license bandwidth fpc port-details 0" CLI.
In below example, only few interfaces have license tier advance (4*100G & 3*10G).
