I'm not sure I see where the issue is, generally speaking some deviation is expected because of floating point errors, or approximations in the physics solver. From what I can see the values between iterations change by a value that is much less than 10^-9 for x and y (below one nanometer!) while the model seems to be slowly moving up in Z (maybe you spawned it a bit too far below ground and now it's slowly moving up to avoid having the mesh intersecting with the ground plane?).
I think you are right as this is expected.
I assumed that just no input of coordination caused it acting up but once you add the input, it shows exact same as it should be.
Maybe this is not worth to mention the issue. Just add x,y,z in the command to avoid the "acting up" numbers.
Thank you so much!
