This can be caused by the Element being stuck in a loop where it simply gets reloaded after sending a Trip Request, rather than populating with response data.
To avoid this problem it is recommended to filter for the sdkLoaded event by including the following code prior to loading the element:
if(event.type === 'sdkLoaded'){
// sdk is ready, create and mount new elements
$sherpa.V2.createElement(....)
}
