What steps will reproduce this issue?

In DateTimePicker, If just change Only Date and click in any blank space of the screen - DateTimePicker panel does not hides. But if I change first Date then Time and click in blank space, DateTimePicker panel gets hide.

<UserControl x:Class="MainModule.Views.Utility.DateTimePickerControl"

             xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
             mc:Ignorable="d">
    <Controls:DateTimePicker 
                             Background="Transparent"
                             HandVisibility="{Binding SelectedItem, ElementName=DateTimePickerHandVisibility, Mode=TwoWay}"
                             IsClockVisible="{Binding IsChecked, ElementName=DateTimePickerIsClockVisible, Mode=TwoWay}"
                             IsEnabled="{Binding IsChecked, ElementName=DateTimePickerIsEnabled, Mode=TwoWay}"
                             IsReadOnly="False"
                             Orientation="{Binding SelectedItem, ElementName=DateTimePickerOrientation, Mode=TwoWay}"
                             PickerVisibility="{Binding SelectedItem, ElementName=DateTimePickerPickerVisibility, Mode=TwoWay}" 
                             Controls:TextBoxHelper.UseFloatingWatermark="False" />
