Everyone on your account should be viewable. However, you have to choose "Select a User" on the far right. Depending upon your screen size, this may be off the screen to the right a bit. After clicking on "Select a User", this will then pull up a list to choose from. By default, you are the only person that can be on lines 1 and 2, so that is likely what you are seeing as just your name and extensions showing. I am attaching a view of where you should click to choose users.
