Duplicate Group Titles
First, I LOVE this plugin. I don't know how I survived before. Also, I apologize if this was already posted, i didn't see it, and I'm happy to be pointed to it if so.

I'm getting duplicate group titles and I can't figure out why.
For example, I have two symbols named:
icons/advice-off
Icons/share

But they are showing up in different groups; both called "icons".
