ddfilelister - listing gets messed up when moving files

I've noticed that the current file listing gets messed up when moving files from the current listing into another directory. Moved files' partial filenames sometimes show up at the end of the list and/or the last entry sometimes gets doubled or shows up without a description until you highlight it. An activity that refreshes the screen like viewing the help screen, or deleting files will fix the display.

In the attachment you can see the partial names of files I have moved from the directory - at the top of these is the 'door' file that is duplicated from the last file in the list.
