Oh I thought you have already submitted and your error check showed everything is filled. So if you did not submit yet I really don't know, for my case when I wanted to submit everything was fine, the error check showed me all is filled no empty fields, so I went ahead and I submitted, after that when I checked the "submitted application" some fields were missing but after 4 days they came back, I don't know about you since you did not submit yet, I guess with the 7 day extension you have more time, so don't rush, take your time, wait for their reply or call them, don't do sthg you regret later! Good luck to you!
