When I change the Grid & Ruler Settings on the Drawing Aids panel from inch to millimeters, they change back to inch when I reopen the document. Also, the value changes completely. One example: when I add a horizontal guideline of 10mm, then I save the document and reopen it, the units change to inch and the value to 3.4792in, which is 88.372mm. So instead of 10mm, I now have a guideline on 88.372mm
Does that bug still exists in AEM 6.4? Is there a solution to that?
