Player Model Legs Misaligned

The legs of the player model are misaligned with the torso in all versions between 1.18 rc3 and 1.6. (unable to test versions between 1.6 and 1.0 due to crashing)

The issue also affects mobs with similar model such as zombies.

The player models in the laucher is properly aligned in contrast.

Have tested versions 1.18rc3, 1.17.1, 1.9, 1.6, 1.0, beta 1.8.1, beta 1.0, alpha 1.2.2a . Issue only present in 1.6 and above. All versions bellow 1.0 are properly aligned.
