The driver station buttons just select what directory/program is the dashboard program that the driver station starts. So if you have the java plugins installed on the computer then select "Java" and it will start the dashboard as <userdir>/sunspotfrcsdk/tools/smartdashboard.jar.

Where in your program are you writing the throttle value? Make sure it's somewhere where it's continuously being executed so it will always be sending the current value.

I'm not exactly sure why it's disappearing from the screen unless, as was suggested, you're running in "Test" mode which puts up a different screen on the dashboard. Teleop and Autonomous modes will display on the same screen, so be sure you're updating the value from both of those paths.
