Error displaying the time format when selecting it from the filter

I changed the time display format to d/m/y, but when I select it, it reverts to m/d/y. Is there a way to change it back?

Followup, I read the linked issue and apparently the date/time format in filter widgets is controlled by your browser locale settings. Check your system settings for the ability to change the format of that value, if supported by your operating system.
