Events not showing on some embedded calendars

We use Zoho calendar on our webpage to show events for our users. On our home page, we provide a short 3 day view of events, and on our calendar page, we show agenda, weekly, and monthly view of events. Events for tomorrow (Feb. 1) are showing on all three calendars on our calendar page, but not on our home page.

I've tested be creating new events. If I create it for Jan. 31, it will show up under today. If I create it for Jan. 31 and span to Feb 1, it shows up under both. If I create it just for Feb. 1 (or Feb. 2) it doesn't show up at all.

I played around with the sharing settings for the calendar, and noticed that some of the embeddable calendars exhibit this problem, while others do not.

You can see this in action here:

- https://calendar.zoho.com/embed/506538d0e7113b8c59bb8f65eef70ec0313aefb4938188318d4fc1b08aa33b6c4a64100d17cdc3bb?title=events&type=10&l=en&tz=America/St_Johns&sh=[0,0]&c=0 - This is currently on our homepage, and is not working correctly.

- This is our week view and shows things correctly: https://calendar.zoho.com/embed/506538d0e7113b8c59bb8f65eef70ec0313aefb4938188318d4fc1b08aa33b6c4a64100d17cdc3bb?title=events&type=1&l=en&tz=America/St_Johns&sh=[0,0,0]&v=1

- This is another 3 day widget, and is missing Tomorrow's events: https://calendar.zoho.com/embed/506538d0e7113b8c59bb8f65eef70ec0313aefb4938188318d4fc1b08aa33b6c4a64100d17cdc3bb?title=events&type=9&l=en&tz=America/St_Johns&sh=[0,0]&c=8

- But here is an agenda view, and does show both events for Feb. 1: https://calendar.zoho.com/embed/506538d0e7113b8c59bb8f65eef70ec0313aefb4938188318d4fc1b08aa33b6c4a64100d17cdc3bb?title=events&type=7&l=en&tz=America/St_Johns&sh=[0,0]

Anyone have any insight as to why this may be happening?
