HEADHUNTER RENGAR CHROMAS use base skin's E ability SFX

So I was messing around with Rengar in Practice Tool using the red chroma for his Headhunter skin and noticed his E- Bola Strike sounds like the base skin's. I started another game using the same skin but without the chroma and it's different. I think it's been like this for the past few months.

I just noticed this now because I rarely use Headhunter Rengar without a chroma and completely forgot his E is supposed to have like a chain sound. Hopefully this gets fixed soon.

EDIT: I just checked again and it turns out even the start of his R doesn't use the same SFX.
