Annoying Preset Menu

Somehow I have managed to change the menu that I get when I click on the bar that shows the present preset.

I wish to select a different preset and this HUGE GIANT SQUARE-LIKE MENU pops up with 3 or 4 columns of options.    It shows just about every possible preset there is on a single page but it also has scroll bars if what I want is not on visible.

I have no idea how it got like this but I wish to get back to the nice compact, small window that opened up prior to that.

Can someone give me a clue as to how to deal with this ?

Thank You
