"Now Playing" widget not disappearing even after iTunes/Spotify/Safari is closed

Describe the bug
I loaded up the Golden Chaos preset and it was working perfectly until I restarted my computer. Since then all of my app-dependent widgets including all "Now Playing," iMessage Notification, and Events Notifications widgets appear on my Touch Bar despite having no media playing or having the apps closed all together.

  • Type of Mac: 15 inch MacBook Pro 2018
