Added a .MOV file but software added to/treats like audio file

I've created a project with over 300 jpg files. Currently have 2 .Mov files imbedded in project in the appropriate places.  Attempted to add another .Mov file but Elements adds it next to the audio files instead of inserting the .mov in the location selected. 
 Can't figure out why this .mov file is being treated like an mp3 file. Appreciate input/ideas to resolve.
