rotation animation causing objects position to move

Hi, I have an object that I have animated, all it does is slightly rotate back and forth, when i play the animation in the animation window, it works perfectly. But once I play the scene, for some reason the object moves its position slowly. But there is no change in the position in the actual animation, and I cannot figure out why this is. Anyone possibly have an idea why?

 

maybe using rotation instead of localRotation or position instead of localPosition?

Uploaded a video that might help explain the issue better

Edit: I will have a look at the local/global positions. thanks for response

 

waiting for same answer, applying root motion not helping me

 

If you found a solution, I-m interested, I-m facing the same problem
