Sometimes Kpop groups in american talkshow feels out of place

Not all shows, but there is one particulary that I feel everytime idols are visiting they feel out of place. You know The Jennifer Hudson show? Nothing wrong with the host, she is polite and very friendly. But the outro thing they are doing when the celebrities walking down a hallway and the staff are singing their exit of the show, it doesn't fit with Kpop groups. The groups I've seen going out feels like they just wanna leave quickly lol.
