views and initial_view are not respected

Hi there,

I use the shortcode below but the initial view is still the default monthly grid and not the list showing the next 10 days. How can that be?

[pretty_google_calendar gcal="xxyy" locale="da", list_type="listCustom", views="listCustom", initial_view="listCustom", custom_days="10", show_today_button="false"]
