Unsealed Spellbook Smite zero damage bug

I was simply playing my support main. With the new rune, unsealed spellbook, we have a faster uptime on flash. Also the massive amount of options to change our summoner spell is unheard of. After the jungler died, the team was hiding to baron, and I panicked and change my exhuast to smite instead. The icon displays zero damage, and I was really scared. I smited the wolves and it indicated 720 damage instead. Will there be any fixes along the way? Who knows, singed smite support can be back.

Thank you, Office
