Canon Elura 85 clip import problem

My school just purchased three new Canon Elura 85 camcorders. The problem we are having is that everything imports as one clip. iMovie does not automatically seperate the pauses in recording into different clips. Has anyone else had this problem? Is there a setting we need to change in iMovie or on the cameras? Any ideas or suggestions are greatly appreciated.

Thanks
