I think you are looking at a view where a second calendar has been selected.
I think you may be (you haven't told us) in a 1 day view of the calendar and
2 show side by side.

Click the Calendar icon at the bottom of the left most field on screen (what
was called the folder list in older versions).  You should now see which
calendars are selected for you to view.  Un check the one you don't want.

If that doesn't do it, post again with some more detail - what are you
looking at on screen when 2 calendars appear?  Whose calendar is the other
one?
