Custom templates not working?

Custom templates not working?

Hello,

I am clicking the numbered options to view other formats for embedding my calendar on a webpage, but there is no change in the content below - the example doesn't change, and neither does the preview. Also, the preview opens in a day view starting at 12 midnight, rather than within a range near the current time.

Here is the embed code I am unable to change:
<iframe src='//calendar.zoho.com/embed/cd7813e6bfe12cab5bd7aac54bac0de22eb45570688f58d14bedbf8fef0c96f88cabcad57cbbb1a0?title=Library hours&type=1&l=en&tz=America/New_York&sh=[0,0]&v=0' width='600' height='500' frameborder='0' scrolling='no'></iframe>

Thank you for your assistance.
