I've got a similar issue... maybe this is the same bug.
I'm trying to create a library of strokes with each stroke being of variable width (think of a stroke and using the "Pressure Profile" on it).
I can create a Style Category and add one of my custom strokes to it, but from then on, I cannot add any others.
Another strange thing is that once a style is selected in the Styles Panel, it will remain selected even after deselecting the spline. If I make another document active then go back to my working doc, THEN it will be deselected.
 

I LOVE AG's plugins. I see the difficulty of integrating or adding on as a plugin, but hope something happens. 

Thanks Walt, I figured it out 5 minutes after posting my query. I was selecting the individual paths, then copy/paste. What I should have done is highlight all the layers (in the Layers panel), then copy/paste. Works perfectly!
