Properties: Date format not following system settings

Iʼm here on Linux (Kubuntu derivate “Tuxedo OS”) and set the OS date explicitely to German style and it does not adjust in view mode. The format in source mode is 2023-10-29:

Operating System: TUXEDO OS 2
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.111.0
Qt Version: 5.15.11
Kernel Version: 6.5.0-10006-tuxedo (64-bit)
Graphics Platform: X11

I already restarted the OS multiple times. I would expect Obsidian to take either the system format or a custom style as suggested in Properties: let the user customize the way Dates/Times are displayed (independently from OS) - #52 by barabasz

Thanks!
