Afternoon events are not visible on week and day views but are there in 2 week or month views - can I fix this?

[Jenny_Witterick]

I have 4 plus events in my calendar and only 1 or 2 of them are visible in the week or day views. The afternoon appointments are not visible at all but the first appointment for the day is.
Does anyone know why?
If I switch to 2 week or month view I can see multiple appointments on each day.
