[Gameplay] Full Metal Jayce uses Classic skin's voice

So I started playing Jayce again after the Preseason update and selected his Full Metal Skin. The skin usually filters his voice to have a deep, mechanical sound to it, but all my resent games with him using this skin had him talking in his default skin's voice. Has anyone else been having audio bugs like this? Again, it's for a skin that filters the default skin's lines, not replacing it with other lines like Legendary skins.
