I have submitted my profile on 3rd April 2019 and got AOR the same day. Before submission, I had once saved the application with a Representative name (my friend) later during submission I removed those details and marked Representative as "no". Today after 45 days from AOR I got a message saying more documents needed. I went to the Submitted Application link and saw its asking for IMM55476 Representative form to be uploaded, and in the details section of the request it says "Replacement needed". What does this mean?
