Ezreal AD scaling tooltip bug

I started a game with Ezreal and noticed the AD scaling in the tooltips for his E, R and Q are at 0, which was quite odd because I had enough AD to make the scaling more than 1 (I had bonus AD from Doran's Blade, AD runes and the mastery "Natural Talent". I thought it might have something to do with the fact they are not learned yet, so I learned my q and still, "0" in the AD scaling. I then tried to "Update" the ability to make it see the real value, and even though I used my q and it dealt the right amount of damage, the tooltip still showed "0" bonus damage from AD. This effect later changed for the ult (which later had its scaling working) but the wrong tooltips of Q and E remained even after I bought Manamune. Anyway, something is messed up there. http://imgur.com/a/fAP20
