All Submissions page displaying wrong contest code.

I have observed that on the submission page, the Contest Code column has been displaying wrong code for the problems. Why is it so?

We understand your concern. However, we’d like to tell that the submission page isn’t showing the wrong contest code. Actually, once the problems are moved to practice section, the contest code column on the submission page starts displaying the difficulty level of the problem. Hence, you are seeing Medium, Easy, and Hard in the contest code column. We hope this will clear your concern.
