Face of the Mountains money thing isn't working with Kalista's auto attack passive.

I was playing as Alistar as a support for Kalista my last match. I had bought the first item for FoM (can't remember it's name) as my first item, along with a health potion, green ward and yellow trinket. I first noticed that the Passive was killing the minion but no visual or sound conformation of the gold being obtained. I then found out it was only happening to minions with Kal's Passive where if we both attack the same target within a time it will deal extra damage. I tried to see if I was actually obtaining the extra gold but I couldn't clearly see. I never asked Kal If she was ever obtaining the gold. This would have helped a lot. But as it is it's very obnoxious not knowing. End of game not only I but also Kal was severely under the gold average of what is normal for our roles hinting that even though I last hit them no one was getting the gold for it. This is a sever game changer and would love it to be fixed as soon as possible. Also side note when Kogmaw kills someone with his passive who has a buff he will have the buff on him when he revives and the visual for it retains the entire game (scared the Ahri into thinking I was hacking), it won't have the active by the champs Hub just the Swirly Visual of it will be there. And I would love to tag this properly but I cant find where to tag it...
