Renamed Custom Enchantments

[bca_]

I recently bought a custom enchantment on /ah but it was renamed. Because of this it does not work. Is there way to undo this, or is it permanent? If there is no way to undo it is it a bug?

Any custom item (sell wand, angel/fixing dust ect) doesn’t work after being renamed.
I’m not sure if anything can be done about this, sorry :/
