Moving layers between AF docs

[iMacatemyphotoshop]

I grouped layers from one AF photo doc, then duplicated the group since the program seems glitchy, then dragged the whole group to another AF doc. When the group got to the second AF doc, a green plus appeared, so I released the drag. I've done this over and over, but instead of moving the layers from the first doc to the second doc, the result is that an unrelated layer in the second doc duplicates itself. Is this a defect in AF, or is the deranged hacker who has wasted hours of my life making the program not work as it was designed to?

Is it possible for you to provide a screen record or screen shots showing this issue when you are copying over the grouped layers.
