Problem with display settings changing

I have a user with a Lenovo X230 running Windows 7. She uses a docking station so she can use  dual monitors. Twice this week she has docked the device and only one docking station is displayed. After some troubleshooting I found that in the display settings it showed,
 " Show only on 2" . I had to manually change it to "Extend these displays." She is not savy enough to have went into the settings to try to change the displays so I wasn't concerned after I changed it back until it happened again. What might be causing the display setting to change fro extended displays to show only only 2?
