Possible bug with the "Predator" rune

I've noticed two in-game bugs with the "Predator" rune.

• Visual bug: it does not display the dmg the rune actually does, it's just the generic text from the rune forge page.
• Damage bug: I've tested with **Volibear ** at the 4-minute mark and the additional damage will not proc. I've tried with just **AA ** and with Voli-Q but the additional dmg from "Predator" will not proc.

You can see some numbers in the picture in the link. I can upload a video if it's needed.

Can someone please take a look. [sg-zephyr]
