Red mags #metal regen block not working

Just coming back to game after a long lay off, so maybe this nerf isn't news? Red mags vs penny Parker in battle ground had masochism node, but she is #mental. I though as it reads in his abilities that he has -105% against metal champs meaning they won't regen in fact they will degen a small amount? Not the case here

There’s another node at play here.

Edit: while also possible that she is #mental, she is definitely #metal.
