Evidently "Tennis und Golf" wronged, because the next men's edition will be the 98th edition of Bavarian International Championships (started in 1900s), as you can see in Official Website:

Could it have been changed back retroactively?

Here's what I can add to your honor roll of the Western Province Championships. it comes from pages 64-65 of the
South African Story, by Russell Eldridge in 1978.
I've printed them as they are in the book. You could, in my view, put 1905/06 as 1906 as long as we make clear it started late one year and ended early the next. So perhaps 1924/25 could be 1925 (Jan)
