I think I found a bug, but I'm a newb, you guys tell me..

The first image shows my layers stacked up with no cloud layer. The second image show what happens to those layers if I create a layer with a combined cloud color and opacity image, with or without touching the opacity slider. If I create (and display) a layer with JUST the cloud opacity layer, it does nothing, regardless of the opacity slider. If I create and display a layer with just the color layer (and display it), it makes the same mess in the second image.

So, as long as both offending layers are hidden, I get the expected results. If either of them are showing, it looks like.. the computer barfed up terrain and clouds??

Is this a bug, and does anybody know how to set the cloud layer (or others) to show opacity, without blending opacity and mucking up the rest of the layers?

UPDATE:

Yeah, I'm pretty sure that this is a bug.

I created a transparent version of the planet symbol above, using black as the mask. I then imported the PNG file as the color image in a new layer. Here we can see that the 100% transparent portion of the layer acts as normal, but the semi transparent areas around the rings, cause all of the layers below it to become semi-transparent.
