E4402B Option License Key

I am using a E4402B with 1DS, 1D5, IDN and 1DR option factory installed, appearing on the serial number tag. But I found the license key is missing from the license check screen but appearing on the hardware list screen. Is it normal?

I've also noticed if I want to install option UKB, I could get into SERVICE and turn the low frequency extension on without submitting the license key. The firmware version is A14.06 for this unit.
Can someone shed some light on the confusion. Thanks in advance.
