Correction to Date - 1993 Silver Dollar Australian Coin [solved]

This Landcare Commemoration Silver $1 coin from Australia came in 2 different versions.

https://en.numista.com/catalogue/pieces70164.html

However both versions should be dated 1993, one of them (KM# 208a.2) is dated 1994 in error.

The one with 20,000 mintage KM# 208a.1 has interrupted reeding edge
The one with 5,000 mintage KM# 208a.2 has full reeding edge

Reference is Greg MacDonalds Book, Australian Coins and Banknotes, Edition 23 Page 167

Can this be corrected please?
