Chaged Skills on ethereal

I have just got an Ethereal Unique item (Spellsteel axe), where its charged skills are not in full number. I know for ethereal items their durability is always spawned full, so I have intuitively been thinking charged skills on ethereal are also spawned full, but now it seems not. Do you know is this by design or a bug? If it’s by design I’d say it’s a very bad one

doubt its a bug, most likely just design oversight and forgetting about it. i dont think they have a system in place for modifying the values of a modifier on an item depending on other modifiers/flags
