In Photoshop CS5, some of my rectangular layer masks are creating a lighter shadow like bandin just below the top of the mask. No effects are applied to the mask. How do I correct this issue?

Have you figured out the issue yet?
Things that might have an effect could be Layer Masks on a Group in which the Layer resides, higher Layers with Knockout settings, … but to make sure it’s not this Layer’s Layer Mask itself could you post a screenshot of it?
