trouble I'm in?

i wanted to reshuffle my preference list in du portal so i reopened my application for making that particular change today. but after locking my profile, i got automatically redirected to my form - which had no other option than to print it/download it. then i thought! oh! this must be it! they may not be allowing any other changes, but I'm finding out thru reddit that they are still allowing changes in application but i was, for some reason, not able to. 😭😭😭😭😭😭😭😭
