As @A_S suggested you can try to collect everything possible. Especially the original documents. Just print out the copies of the same application you submitted. Don't have to fill in a new citizenship application.
They also have a procedure in case they misplaced an application, at that point they request to see if they can get another copy of everything from the applicant. It could be that or anything else, we can only speculate.
But if they have had any real issues with your application they would've typically asked for additional documents. That doesn't seem to the case here.
Don't worry too much, just bring everything they're asking and you should be good.
