My pancape cape is invisible when I use the elytra

Basically, the Pancape is invisible when I use the elytra and I don't really know why. I'm not sure if it's just me or if it's for everyone or if it's just the world I play in but my Pancape is invisible when I equip the elytra. It works for every other cape like the Founders Cape just the Pancape that is broken.
