Is this a bug or am I doing something wrong?
I’d guess the second.
But then you don’t seem to give enough details to judge what you are doing and what could be the issue.
Could you please post a screenshot with the pertinent Panels visible?
I think I discovered what my problem was caused from. When using the frequency separation technique I used on the top layer an apply image command which looks like a high pass filter has been appleied. When setting blend mode to linear light on screen I get an image which no longer looks like it is being covered by 50% gray. When attempting the stamp visible command on this layer Photoshop interprets the top layer as hidden thus causing my problem with the stamp visible layer. On top of my last frequency separation layer I added a curves adjustment layer and immediately applied the stamp visible shortcut which created a layer where the previous layer is no longer hidden and I'm able to use tools for further adjustments. Short version I was screwing up.
