When using /give or other commands to give armor with blast or fire protection enchantments, the armor has generic protection instead. Regular enchantments were obtained using /enchant command. All enchants were done with diamond armor.

I changed the enchantments to their numerical ids and the enchantments still do not get anything but protection.
See MC-61041 and @unknown's comment.
Enchantments still use numerical ids.
