Playing SD card music in Amundsen

In my previous Octavia Amundsen system, whenever you returned to playing music from the SD card it always started at the exact spot (album/track) where it was when the media player was last used. In the Amundsen system on my new Scala SE L it does this if it's on the same day, but if the media player has not been used for a day or two, when switching on, it starts up with the the first album by an artist name beginning with A. I then have to go into the listing to return to the album I want. This is infuriating! Anyone else had this problem? Can it be fixed? Why does it happen (it's the very same SD card plugged in via a USB adaptor)?
