Calendar "monthly" view not showing all of the appointment data

Hi there,

I was wondering if anyone else is experiencing this or has a fix. When I look at the weekly or daily view of the calendar, I can see all of the appointments for that day. See below…

When I switch to the monthly view, not all the data is populated. In this example the 10:00 appointment is left out. See below…
month

If someone can assist, that would be great. Thanks!
