Bug? calendar bar on UI can wrap

From the UI screen (not logged in) sometimes when you click on future days on the calendar bar, the calendar bar will jump to two lines instead of one. I don’t see a reason for the wrap to happen. Known problem? While I’m at it, is there a reason for the big empty space above the calendar bar? It would be nice to move the calendar up, so more of the day’s programs will display. As it is, especially when the bar expands 2x its normal size, there’s only two or three lines of the program list visible.
