touch bar not changing with apps

My Touch Bar is functioning but when I open different apps like safari and Microsoft word it usually changes with the app. Ive looked everywhere and can't seem to find an answer. I have tried. going in activity monitor but the Touch Bar agent isn't showing. I have tried writing in terminal a specific code mentioned on another post here but it didn't do anything. I have recently downloaded lockdown browser because my school is requiring it for a course. I am not sure if that has to do with it.
