Just double checking, did YOU leave feedback for the client? His for you will NOT show up until YOU leave feedback fror him, and the screenshot would suggest that you have not done so!
Today would be the last day you can leave feedback as it is only within 14 days.
If you do NOT leave feedback for the client today, his feedback for you will show on day 14 after the contract ended, so tomorrow.
Please, go to My Jobs page and scroll to the bottom of the page. You'll see the ended contract with the request to leave feedback. As Petra posted out you only have one day left to provide feedback on that contract.
