Ever since this new semester started, I have been unable to edit my courses with different nicknames. I have a science class with a lab class that their names look identical at first glance and I just want to specify which is the lab class. I was able to edit the names last semester but for some reason it seems like that option has been removed. I can't seem to find the settings tab for the courses anywhere. Was the feature removed or am I looking in the wrong place?

On a separate note, my Canvas courses tab shows I am enrolled in a class I took last semester. I'm not sure how to remove it.
