I did talk to the developer of Week and he said that it worked find on unjailbroken iPhones. To me it seems that the font size is too big for the allocated space.
For instance in Week (which shows the week number) we know there are only 52 weeks in a year so the space allocated is for two numbers. But once you get beyond a single digit you get three dots following the single number (i.e. 3 . . . )

Hearts acts the same way - no problem with single digits - but over a single digit - the (*)&(*& dots appear.
