(Bosses) "A The Wither fight" (and related issues?)

This message shows when a wither fight starts. It might make more sense if the wither boss was simply called "Wither" instead of "The Wither" (especially as the vanilla boss is simply called "Wither", not "The Wither") Also consider the ender dragon (if it says "A Ender Dragon" that wouldn't sound right), I usually keep boss notifications off so haven't paid attention to this See screenshot
