Photoshop :: CC Not Play Layer Adjustment Actions Correctly?

My computer has PhotoShop CC installed on a brand new Dell Windows 7 computer. Previously I used CS4 and it worked great, but now I'm having issues with CC playing back any Action that has layer adjusments. I'll record an action consisting of an edited layer adjustment such as curves, levels, brightness/conrast, etc., and then when I play it back the layer adjustment applied is the default 0. For instance, here I clicked "Create New Action" and labeled it "Curves Layer TEST":
 
add a new curves layer adjustment and label it "Brighten":Then I add a few points to the curve (overly brightened to demonstrate my issue):

then I hit the Stop Recording button. But when I look at the curve values in the Actions box of the very curve layer I just recorded, it says the Preset Kind is Default. Why doesn't it say Custom??? The Properties box read "Custom" as I was editing the curve!

and nothing happens to the image. it now has a curves layer on top, but it's the Default straight line. What happened to the curve I edited and recorded!!??
 
What's the deal? This is the same process I used in CS4, CS2 and every other PhotoShop incarnation and it worked fine, until CC. Is this a bug? Or is there a new process to creating layer adjustment actions???
