Triumph gold bonus bug

I'm not sure if this is just the tracker messed up or if it's not giving the gold at all or not, but after reviewing my match history, and looking at the runes tab, Triumph bonus gold is stating 0 gold granted on each page. My understanding it's supposed to give 20 bonus gold per takedown and it's simple to do the math on that, but just isn't showing for me already calculated. I'll be paying attention to see if it does grant bonus gold in my next matches during the game now though. https://prnt.sc/kdc2ta
