Hi,
I have noticed that in the MacOS version, if you use the little up/down arrows next to the ‘Pass Count’ field in the ‘Cuts’ panel, the number of passes doesn’t actually change to reflect the new number. I have to double click the cut layer and change it there for it to stick.
For example, I had a layer set to 2 passes and clicked the little down button to make it one pass and it still did two passes even though it visually changed to 1. After double clicking in the layer and explicitly typing a 1 over the top of the existing 1 and closing the window makes it stick and does 1 pass. It seems to be repeatable.
