Bug description:
Originally when I click the "Cancel the label" menu, the Curve frontend will send a request http://localhost:8080/v1/data/live_data?startTime=1528030800000&endTime=1528063200000&action=cancel_label. But it does not actually work and the server does not clear the label. This PR fixes the bug.
