Intro guide still thinks Brutalizer builds into black cleaver

So today I was playing with my friend who just started league and I played a few rounds with him on intro bots. During my game as Leesin, I noticed that it said to buy Brutalizer for Black Cleaver. I clicked to see the build for Black Cleaver to make sure riot didn't weirdly change it, but it said phage, not Brutalizer, built into Black Cleaver. Not a huge bug, I just wanted to point it out because it annoyed me. :P
