Style Tab Missing in Calendar View

I am having an issue with the settings when using the widget in Calendar view. I am using the widget on the Home page of the website in List view and I am able to access all three of the settings tabs. I also have the widget added to the site’s Calendar page in Calendar view. When I am in Calendar view, the Style tab of the settings is blank. How can I resolve this issue, so that I can adjust the Style settings when in Calendar view?
