The headline that’s being played isn’t the one that Chartbeat says won the test. Why?

Chartbeat can only start playing winning headlines on your page if the Heads Up Display is both installed and enabled on the page that originates the headline test. While the HUD is enabled it checks Chartbeat’s APIs about every 60 seconds to get info on experiments running on the page, including any winning headlines for finished experiments, so it’s necessary for the HUD to stay enabled for winning headlines to play correctly.

When the HUD is turned off, it defaults to what’s dictated by the CMS which might not be the variant that won the experiment.
