Student Finance - Evidence

When I did my SF application I had a few things to do, like send off my passport etc, and then ALSO I wasn't initially able to locate my course code so that was another step I had to update once I got hold of it.

I sent my passport along with the other important documents off, and the SF application updated to say they got it and I got it back within 2 days which was great.

After this I updated my course details as I finally got a reply from my university, so once I located my course the application updated again. Due to this update it's asking me to send my passport and evidence in again, like it did initially before I sent them off.
Do I actually have to send it all in again, or is this just what happened because I updated my course details and it doesn't matter cos they already received everything they needed to?

I want to say I submitted the application 2 weeks ago on Friday and then I sent the passport off the following Tuesday. And yes I do believe it was accepted!
