Some things KG does will never make sense! Like when they asked me to pay the RPRF when I already paid it a year ago! :
To me, it doesn't make sense to fill out three seperate forms, especially since you only had to fill one out for the original application. However, as Halfmoon pointed out they do state
seperate Schedule A's. Nobody knows for sure how the processing works so you can a) send them an email and ask (good luck getting an answer) them if they want one form or three forms or b) do what SweetieQ suggested and do it both ways so it leaves no room for errors.
