Q: iTunes 12.4 selective sync ipod

So, like many here I have the new iTunes 12.4, and like many here, I'm left scratching my head about things that used to be pretty easy.

ALL I WANT TO DO... is modify the selective sync settings for my ancient ipod nano.

Easy-peezy before the update.

Now I can see my nano off to the lefthand side. I can see what's on it. Looks like I can even try to drag music folders up to ADD to it. BUT HOW DO I REMOVE A MUSIC FOLDER THAT'S ON IT SO AS TO MAKE ROOM FOR MORE STUFF? I've tried dragging... I've tried right clicking. Before the update this was a simple!!!
