This seems odd. I will check the Bug Reports and see if there's anything there?

Certainly odd and I hadn't seen any disclaimer about it so I had no idea.

Any info is appreciated. And it's good to pass this "up" anyways if it isn't known.

Strangely on Ayumi the passive doesn't have those levels you see above. Since you say yours is "fully" booked, is the UI actually suggesting you can book the passive? If not, I suppose I'd ask what you were expecting from it? That passive doesn't seem like it should be bookable, so I would guess this is just a visual glitch?

Also has the icon for a sleep debuff, even though the passive doesn't trigger any debuffs.

The listed skill upgrades would not apply anyway, but they do apply when the passive is triggers the A1.  I don't know why they are repeated here but these are the upgrades for the A1.  Note that there is no need to upgrade damage or buff/debuff chance on the passive, as it always works and causes no damage itself.  It merely applies to the A1 (the listed upgrades are identical to and apply to the A1).

Now I can believe it is a visual glitch but why is it still in the game? It is not clear at all and there is no warning about it being a glitch anywhere.

Also it could be that those level ups on the passive impact the A1. I should not have to guess, especially since there are more than 1 case in the game where the wording is wonky and it is not clear how things work/interact when you read them.

Agreed, I don't have that champ or I'd look to see if it looks the same.

I'm having the exact same "glitch" if that's what it is.  It would be nice if Plarium fixed this or at least confirmed it's just a visual glitch and not a mechanic that's actually malfunctioning.

Especially now that he is even on a boosted summon.

Brilliant...
