No submit option in the January Challenge questions after the challenge is over.

Even after sending the January Challenge questions to Practise questions, there is no submit option till now. Is it the rule to not giving the submit button for some days or something else?

Questions in the contests are almost instantly moved to practice section.
You can find them from editorials or in the practice section or remove JAN15 in the question url e.g. CodeChef: Practical coding for everyoneCHEFSTON Problem - CodeChef


Submit tab will be available in the practice section questions and not in the questions from the contests
