I installed tunderbird 128.13.0esr via flatpak on Kubuntu 25.04.

On the system settings I've set the time format to "English (Nethelands)" which uses day/month/year for dates.

Thunderbird settings only date format options are: Application locale: English (United States) Regional settings locale: English (United States)

Can I change that anywhere? I don't want the US date format
