RealCW Texture Pack for Xbox One Bugged Skeleton Mobs

I just purchased this new texture pack but as I was going through it I noticed the skeletons were bugged. Whenever they hold a bow, the bow is extremely thick and does not look right. I am guessing it might be a glitch or an issue from the recent nether update but I was wondering if there was a way to fix this on my part or if it just waiting for the creators. Refer to photos below. Thanks!
