It seems to be happening whenever the full version number is used in the URL, like index-v9.3.0.
When only a single number, like index-v9, is used, the links and list of versions stay intact.
See the umbracoSettings article and related versions, for more examples.
As I remember, this used to work, so I'm not entirely sure what could have happened.
When multiple versions exist for a specific article, the versions will be listed with links in the "Versions" box. Example: https://our.umbraco.com/documentation/Reference/Security/Two-factor-authentication/
When clicking on one of the links, the rest of the list and links appear, and there is no way to see whether more versions exist. And it even looks as if the selected version is now the current version - which in this case, is not correct!
