There are three possible explanations for this movie :

1. Ben 10 Alien Swarm actually exists in a separate continuity, like Race Against Time. The movie could also be an indirect sequel to Ben 10 RAT.

2. Ben 10 Alien Swarm is a "what if" episode to the canon storyline.

3. Ben 10 Alien Swarm is a part of the canon storyline, with several changes made for the movie to suit the story.
