Benj I made some program updates and evidently broke a lot of things without realizing it. I think they are all fixed now. In the process I may have found another issue.
Could you look at one of your Fashioner sessions and open the Layers>Layer Visibility tool? Do you have a duplicate of the Fashioner hierarchy? That would be two sets of Fashioner layers with Draft, Outline, Seam Allowance, etc.
