Ort rune in horadic cube does not restore charges of magic item

An ort rune together with the item you want to repair in the horadic cube is the recipe to repair an item. However if you place for example a teleport staff with 18 charges of 48 maximum in the cube the charges are not restored. Is this not part of the repair proces of a magic item ?

Ort Rune + Chipped Gem will repair the weapon and restore the charges.

Ah ok thx i didn ’ t know this recipe
