Error in Smart to animate, upward displacements.

Recently, I noticed that when creating automatic animations in Figma, during the transition between frames, instead of staying in a fixed position (as it should), there is a random upward displacement, and in different animations, this displacement repeats but at different distances.

I previously had an animation that worked correctly. I duplicated it to verify, and in the duplicate, this issue occurs, but not in the original.
