Issue in Jupyter Notebook: Duplicate UNQ_C2 Line That Cannot Be Edited

Hello ,

I’m encountering an issue in the Jupyter notebook for this assignment: the comment line labeled UNQ_C2 is appearing twice.
When I attempt to delete the duplicate, it seems to be locked and cannot be edited.

Is there a way to unlock, remove, or otherwise fix this duplicated comment line?

Any guidance would be greatly appreciated!

It seems you may have inadvertently modified your notebook. (or done an accidental copy-and-paste).

To guard against difficult-to-debug issues, I recommend you delete your present notebook, and get a fresh copy so you can start over.

Thanks for the feedback.

Can you please provide me more information, on how to delete the present notebook?

Go to the File menu, then use the “Open” option. You will see a list of files.

Click on the checkbox next to the notebook file name.

A red “trash can” icon will appear in the top menu. Click on it.

After that, go back to the assignment page, re-enter the lab and use the “Lab Help” tool (it looks like a question mark inside a circle, in the upper right corner of your browser), and use the “Get latest version” tool.

Then exit the lab and restart it again.

You should now have a fresh copy of the notebook so you can start over.
