File Sequence When Printing from SD Card

Previously, when I loaded my G-Code file onto the SD Card, it would appear at the top of list when I selected Print from SD Card on the LCD. Recently I have noticed that the latest added file is now somewhere buried on the list - not alphabetical or by date. I liked that the latest file was at the top of the list. How do I get that back and what changed to cause the G-Code file to be somewhere in the middle of the list?
