The title is different on the film itself

The title on the box art is "Redemption: Kickboxer 5" but the title on the film itself is just "The Redemption". I hate when they do this. Sure there is some lame story connections to the previous Kickboxer films but why not put Kickboxer 5 in the title of the film. It's like they plastered it on the box just to sell more copies but were too lazy to put it in the film itself. God I hate that.
