[Semi Solved] cannot rotate or move geckolib to center without messing up animations

I have finished an entity and went to test it in-game. The entire model was faced backward and spaced from its origin making its shadow offset.

It seems I needed to move the model in the block bench back to its origin and rotate it 180 degrees. And When I do so, it completely messes up all animations causing me to redo everything once again.

Is there a way to fix this without animations getting messed up?

I am in desperate need to fix this one.
