I had to launch an app called LockDown browser in order to take an exam. Before I launched the app everything was working fine, I was able to use auto correct on my Touch Bar, have a volume/brightness slider, visit what websites I favorited by pressing the website icon, etc. Since I launched that app I can't use any of those features. Help would be appreciated.

Not all Apps are optimize to interact with TouchBar.

If you installed an app that disrupts normal Touchbar function—uninstall it and compare your results.
