  The Seam Allowance reappears
• How To Reproduce the bug
  When the drawing is finished and the pattern is created you go to the 'PatternPart' layout. You will see the pattern created with the seam allowance turned ON. Go to the properties > Seam Allowance and untick the 'Show cutting line'. Click OK and the allowance is invisible now. When you then save the changes made by clicking CTRL-S on the keyboard the seam allowance reappears and the tick next 'Show cutting line' is switched ON again. It does not do so when clicking the SAVE button in the ribbon.
