Wiki file versions are not working

I already created a page in Answers, but never got an answer:

I uploaded a new version of a file for a wiki page. If you download the file it’s different than the one displayed in the list of versions, and also if you go to the image in the wiki page it’s the old one.

The first image is still showing the old file. A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

So the versions don’t work.
