This date is displayed according to the format that is customized at the level of your operating system.
In the Windows 10 region settings, what do you see?
As an examples, what I see for my french settings:
I changed the WIN 10 Long Date format as you recommended and now I get a File Info > File Properties > Date date reading that matches the format shown in the WLE Operation Manual. When one sees the metadata and the screen shot in the Op Manual, it is not intuitive that there is a Win 10 setting at play, so perhaps a minor update to the Manual in the future would be warranted.
