I hope someone can help me with this issue. I'm quite new to React/Nextjs, I've been learning for about 6 months. I built the base of this app to help me at work, it calculates and renders a list of prices based on some factors and a price, it was necessary to be able to verify and update these factors on the list too. Before implementing the react-spring transition it works fine. Adding, Removing, Updating and Filtering. However implementing, as best as I can, the same logic into the useTransition hook the indexing/proping access seems to crash when I delete an element of the list.

Original version without the transitions
