Problems with Event module and drop down boxes

Hello Y'all,

I have a small problem with the Event module. I have in stalled the module properly - because I get the three choises on what node to be displayed in the calendar. But I think there is some kind of flaw in my installation - because when I go the the Node where I which to add the event - something strange is happenning.

The start date shows the month in a drop-down-box as well as the time (both the hour and the minutes), however the day and the year is not in a drop-down-box but in a normal text field.

Is this normal?
