The list you can see is those who have already been upgraded and those waiting who have checked in and have not been upgraded. Since you have not checked in, your name doesn't show, although it is still on the "invisible" waitlist used for upgrades before the gate agent takes over the process using the list you can see. Depending on the flight, your lack of status means you might be well down on the waitlist.
