When you have your Statements set up to show Paid, Pending, and Overdue Icons next to transactions, there is nothing to tell students what the icon means - the column doesn't have a label at the top. There should be a label at the top, or potentially a key that appears to tell students what each icon means. The green and red icons are more obvious, but at the beginning of the term when everything is likely to be grey, there isn't anything to tell students what this means.
