[NWoD Official Sheet] New to customizing, what did I screw up?

So, I've been trying to do a bit of customization on the NWoD Official Sheet to better fit my game(adding a few game lines in the 2nd ed), and I seem to have broken the CSS stuff somehow.  The character sheet is showing up on the Bio & Info tab, as well as the Attributes & Abilities tab.  I'm pretty sure it's the CSS because this happened when I was working on adding stuff to that section. Any advice?

Your CSS cannot do any such thing; you selectors are automatically prefixed with .charsheet to prevent such things. Most likely it's a bug with the VTT; I would recommend reloading the page to see if it clears up on its own.

Sadly, reloading was the first thing I tried.  Maybe I should try starting from scratch to pinpoint the point where it breaks.
