Is mod not compatible with customizable elytra mod?
here is mod list just incase ( I removed all other mods to see if it would work and it still didnt work)

Heres the mod they are referring to. its likely because it changes the "Minecraft" tag at the bottom of the description to customizable elytra as well as other descriptions. would it be possible to copy all the nbt data from whatever elytra is in the elytra slot and set that as the equipped elytra? similarly to how you have set all the enchantments to transfer over? this would probably fix the issues surrounding other mod compatibilities as well.
