Help with Animation Starter Pack

Hi all. I’m just having trouble with one animation from the Animation starter pack that available for free in the market place. The Animation in question is the Fire_Rifle_Hip animation. I trying to play that animation when my PC input for fire is true. So I’ve set up the locomotion graph inside the Animblueprints, I’m connecting a state node (hipfire) to idle and vice versa. I’ve created the required bools in the animgraph, the animation plays, but it doesn’t play like it shows in the preview. The character just goes inside the ground when I press fire. Other animations from the pack work fine. This animation with which I am having a problem is of a type Additive Animation RotationOffsetMeshSpace.
The image below is of the preview, the hipfire animation just has his hands moving a little forward that’s it.

And this is what happens in the editor.

Why additive? shouldn’t you use additive only if you’re using an Aim Space? Also make sure the Root Motion option is turned off.
