Here are six files that show what I am experiencing. When I pick an adjust, for instance BRIGHT/CONTRAST, it appears in the layers display and in the history below that. After the MERGE finishes the layer showing BRIGHT/CONTRAST disappears although it remains in the history. If I click on the SET ADJUSTMENT PARAMETERS, it reapers in the layer box, and remains.
I have gone to view on the content tool bar, scrolled to studio, and tried both with the LAYERS checked and unchecked with no change, OBTW I am using the latest version of AFFINITY.
I am enclosing 6 partial screen shots that should let you see what the problem is. Your interest in helping me is appreciated.
