Date format settings not used in new appointment and calendar view
Summary
Despite the dateformat being set in Edit->Preferences->Calendar and Tasks->General tab->Date/Time Format section to %F %T for "Time and date" and %F for "Date only" the datefield in a new appointment follows another pattern (the one from my $LANG=en_US.UTF-8). I expect the program to honor my wish to format the date like YYYY-MM-DD (%F). Also the date shown in several view in the calendar don't follow the "Date only" pattern. The "list" view does follow the configured date.

This is not correct either but far less annoying.
