unable to unlock and remove certain apps even with using the Terminal.. HELP (pics)

I have been trying to get rid of and delete two apps of mine the "Karabiner Elements" and the "Karabiner Elements Observer". However, whenever I try and put them in my app cleaner app or try to just drag them to the trash can I keep being told I do not have permission and that I need to go to Finder>Get info in order to unlock it

but when I do this the box where it says its locked is greyed out.

Then when I try to change it the system tells me I dont have permission even though I am the system admin weirdly..

After doing some research I was told to try and go to the activity monitor which I did at first and tried to end the item running called the "Karabiner Observer" but every-time I would do it and hit the X button it would just pop back up again almost immediately.

So then I found a post on here telling me I should use the terminal and type in

"sudo chflags nouchg /Applications/Karabiner-Elements.app"

and

"sudo chflags nouchg /Applications/Karabiner-EventViewer.app"

Which I thought would work considering it prompted me to type in my computers password immediately but now even after that it still tells me to unlock it which I tried and it was still greyed out and even tried to delete it both manually and with the app cleaner and both told me again I didn't have permission and to unlock it using Finder>Get info

So I dont know what to do at this point..

Can anybody Help?

Thank You!
