The bows are bigger

Hello, today I come to report a small bug that although it is not harmful is very unpleasant: The skeletons have larger arches as I will send in the screenshot, that happened to me with and without texture packs I also tried uninstalling the game and reinstalling it but it was still happening .

by the way my character did not happen.

I hope you solve it soon, thank you very much for your attention.
