DJ Sona "Concussive" Voice Does NOT Work since 8.5!

After 8.5 and the sound update came, DJ Sona's "concussive" voice does not work properly. Her voice get's cut off immediately. Problem is with the english voice. (Don't know if other languages have a similar problem) This bug happens only in-game for the rest of the game. Only the concussive voice is bugged.
