They wouldn't use three trailing zeros. More likely is that they interpreted 1B as a million million, like the British do, instead of 1000 million.

Maybe a translator thought that it was an error and 'fixed it' adding the extra zero...

Billion means “1000 million” in British English, not “million million” (which is Trillion).

Did they change it?

[Reason077]

Yes, many decades ago. The modern “short scale” billion Is found in UK technical documents and papers beginning in the 1950s, and used in official UK statistics since 1974.
