Route Distances Error in calculation

Have noticed that whne I’m adding in flights across the international date line the calculated distance is all screwed up. For example, YSSY (Sydney) to PHNL (Honolulu) comes up as 19155 miles. Apart from entering these manually, is there a potential bug/solution here?

It’s most likely a problem from the route database. Best other way would be to enter manually.

The wrong coordinates might be returned or entered for the airports. I"ll take a look
