Different Letters of Rec and Submitting to Different Colleges?

Hey guys, I’m really worried about my application. As you guys probably have experience.l lots of schools will require different LoR, so I asked three of my teachers to submit recommendations on Naviance. Now, the first two teachers I asked have submitted theirs, and by default every school has received the first twos’ letters, and I can’t submit any third teacher’s recommendation to any school. The Common App policy is to not allow you to remove old letters, so what can I do?
