Kopia UI using wrong date and time format

My Windows PC is set to Europe DMY 24-hour. Yet KopiaUI keeps making and representing snapshots with US MDY am/pm. I cannot find where to change this. I would actually prefer some YMD setup like ISO.

Anyone knows how to do that.

My OS is set to English and the Date/Time format to German.DMY 24.hour.
KopiaUI correctly shows the snapshots in 24-hour format.
