Next time let the officer know you just received a ticket for the same thing 2 hours ago and you are going to get it fixed. Most officers won't write another ticket.
But since it's too late for that, you should order the extra front plate and install it. Then get an officer so sign off both fix it tickets. Then take both tickets to court and let the Judge know you got them with in 2 hours of each other. Most judges will dismiss one and you will have to pay an administrative fee for the other one.
Two fix it tickets on the same day will usually result in one getting dismissed. Set them both on the same day in court.
