Corporate Mundo quotes not working

Hello,

I am a Mundo main and I purchased the Corporate Mundo skin a few years ago now. I recently returned to League within the past 4 or 5 months and after a patch or two I have noticed that my Corporate Mundo skin seems to be faulty. The skin itself visually is fine, but he does a mix of his Corporate Mundo quotes and his normal Mundo quotes. In fact, it's mostly his normal Mundo quotes. He says the odd corporate witticism, but I find them rare. This has been ongoing for probably 2 or 3 months now. I tried googling it but could not find anyone with similar issues. Do you know how to fix this? Thanks!
