"Key 1" text in calendar

I've got the calendar module installed and configured and it seems to be working all right except that just above any event posted to the calendar the text "Key 1" appears. I assume there's some color I'm supposed to select somewhere that is currently undefined. Where can I set this?

Incidentally, I also managed to change the way the calendar displays from the larger full-page look to the smaller look intended for display in a side bar. I've played with the block options -- changing the view type of the block to something other than calendar, but nothing seems to work. Thoughts?
