If you use Everest cast with SHOUTcast Widgets, there's an important setting that must be unchecked in order to display current artist data. The settings adds the current DJ before the track name. SHOUTcast Widgets is unable to remove this internally since the DJ name changes and Everest cast does not yet have an API related to this feature.
In your Everest cast panel, click on Settings in the main menu on the left. At the very top, look for the section Show current DJ name in metadata and make sure this is unchecked.
