Microsoft made an awesome setting for regional settings, but it doesn’t work. Although I did set up it correctly ( I thought ), the settings weren’t applied.
I already saw those wicked red lines on the bottom of the field settings, but I ignored it. NEVER EVER ignore it 😉
By default al settings are “not applied” ( red line ). When you press F6 the bar becomes green and your setting will be applied! With F7 you can disable it. That’s it!
