Custom items - Flameberg custom effect does not work (and possibly also other items)

From what another player told me, the Flameberg's "custom enchant" (setting the player on fire while holding it) does not work. There are 3 swords with custom effects listed. Flameberg - sets player on fire Broad sword of forest - Regen 2 while holding Vampiric Sword - Wither 1 on successful attack Some of the custom items did have their effects removed (from last season), not sure if these 3 were meant to stay or should also be de-listed.
