Hi Leanne,
Thanks for getting in touch!
Sorry for the confusion here! The Events Calendar actually only comes with one template option: Default Events Template. All the other options are ones provided by the theme, which The Events Calendar recognizes and allows you to select.
In other words, all the other options you see in video are ones where the theme being used in the demo had additional page template options. The Events Calendar itself only offers the Default Events Template.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
