Interface issue with stackable cards

[Alash]

So the other day I was messing around with Lackey's interface, revising the buttons, changing color themes and so forth, and I somehow managed to change the way in which cards are stacked in the window on the right-hand side of the screen. Where previously cards in my graveyard would overlap so that only the card names would show, they're now split showing the full cards one after another. Although informative, this is quite unpractical for graveyard interaction, scrolling through your library etc., so I want it reverted.

But I can't for the best of me figure out how to change it back. Any clues?

Main screen:

Bottom right corner, CLICK Fan Off
Click on the library all spread out, drag up
CLICK Fan on
