Unity XR Hand Transform.position y axis incorrect

I'm trying to get the position of my hand using the xr toolkit so that I can spawn a prefab at the location of the hand. If I do ".transform.position", it gives me the correct x and z axis, but the y axis is constantly changing. Sometimes, it's at the correct y axis (the correct y axis is usually at 0.5-0.9), but sometimes it gives me the completely wrong y axis (When the y axis is wrong, it starts at about -5.0, and then keeps going into values such as -15.0, -30.0, so it's constantly increasing). I've attached a picture of the problem.
