Shield Animation Glitch

So, me and my friend were playing in an experimental survival world (All experiments were on), when I noticed that her shield was acting up. It was somehow phasing through her player and it was on the wrong arm up by the shoulder. I don’t have a picture at the time, so I’ll provide a quickly sketched diagram instead. Also, I don’t know how this happened, as it is an animation glitch, so I sadly can’t provide steps to reproduce
