Incorrect BTJ airport location

I found a heavy mistake for the BTJ (Banda Aceh - Sultan Iskandar Muda) airport location, which should be near the northernmost part of Sumatra island. As a result, the range from LGK to BTJ heavily increases into more than 800 miles, from what should be less than half of that range. Is there any solution for it?

Note: I try to avoid MES, SUB, and CGK, due to heavy competition and very high gate lease cost, so BTJ is deemed as suitable for my Malaysian operations.
