LocRot is location+rotation, I wanted to make sure that wasn’t interfering with what you had going on.
Now, it looks like you included scale at the least in your animation. I would redo setting the animation keyframes, make sure that when you press i to set the keyframe, only choose rotation from the dropdown menu. That way both scale and location are left alone by the animation.
Or if you want from the action editor you can select specific keyframes for the scale and location channels and delete the ones throwing your animation off. An example below shows the screen you would be looking for.
