Zac's E does not indicate range

I just played zac like 2 days ago and I didn't notice this bug until I played a ranked match today. The E does not indicate the max range. Normally while you're charging it up it shows the max distance your E can go, or if you hover your mouse over the ability. I didn't think this would bother me much but it really affected my gameplay so please fix this so I can play zac again.
