I have tried submitting the lab multiple times and have attached a screenshot for reference. Despite following all the lab rules, I encounter an issue where, upon opening the notebook, it shows two notebooks in one. I’m unable to delete the second one due to the mandatory grading system section. Although I have passed all the tests repeatedly, I keep getting an error during submission.

The first lab was completed, but another lab started within the same notebook. As a result, the grading system fails to accept it.

It seems you somehow duplicate some cells. Here is the guide on how to get a clean copy of your Notebook. But please note that it will also remove your code, so, you may need to download your old notebook or copy your code somewhere else.

Perhaps you had an unintended copy-and-paste.

If you don’t have a checkpoint that you can restore, then getting a new copy of the lab is the best option.
