Hey @Jacqueline,
Thanks for reaching out! On the page you linked to, it is not a view of The Events Calendar. That seems to be a custom view from your theme, or perhaps something else together.
So, to ensure that all of the proper event dates show on that custom view, then unfortunately that custom view itself needs to be updated to include the proper event data.
Do you know where this custom event view is coming from? If a theme developer built that, I would recommend contacting them for assistance with modifying that code there.
Thank you,
George
