Anyone noticed the leveling up bug?

When you lane against someone, (you can notice the bug early game mostly) when a player on the opposite team levels up, it shows the next level but doesnt play the sound. It only plays the sound in around a minute or so. This might not happen to you, but it is happening to me. So if it is happening to some other people, I'm just wondering if the sound is behind or just the number changes too early. Thank you for reading this, I'm out.
