Just noticed this bug report. It's not a bug. You don't explicitly set the regional format in the installer, but the installer 'guesses' that setting based on the time zone location. So if you state Brussels for time zone, it seems to pick the de_BE.UTF-8 locale.
If you want something else, e.g. Dutch: 1. Install the Dutch language (to have the applicable locales generated) 2. Select Dutch as the region.
