Wrong mintage in Australian Lunars Series One Proof's and BU's [solved]

How is it possible, that Proof has 1,000 mintage?

Planned mintage was 2,500 and declared: 1,665

Also noticed, that other Lunars Series One also have wrong mintages. Proof's should be not 2,500, but what was actually declared. Same with BU.
