My Steam Deck Cont ID doesn't start with either MEDA or MHDA

The instructions for replacing the left thumbstick on my Steam Deck says the following... however, my Controller ID starts with MLCB? Anybody know why that might be?

• Each Steam Deck ships with one of two different models of thumbsticks, Type A or Type B. Although nearly identical, capacitive touch capability relies on the correct type to be installed.
• To identify which replacement thumbsticks you need, navigate to Settings → System and check the Steam Deck Controller ID.
• If the Controller ID starts with "MEDA" that device needs Type A thumbsticks.
• If the Controller ID starts with "MHDA" that device needs Type B thumbsticks.
