How to reset timepicker?

I have a dashboard with a panel with a table that depends on $time_tok.earliest$ from the time picker. I have an option in a dropdown, token=deployment, to reset the time tokens and thus hide the table:Deploymentchoice1choice2choice3Select When I select this option to reset the timepicker tokens, the table is successfully hidden, but the time tokens aren't being set when I click Submit, so the table is never unhidden. How do I achieve this?
