@AlvaroA The issue with the harness layout where the work area overlaps the header can be fixed by reviewing and adjusting a few settings. First, ensure the "Header only" layout is properly configured in the Harness rule, with the header section placed explicitly at the top and the work area positioned below it. Next, check the associated Skin rule for formatting issues—make sure the header has enough height, padding, or margins defined to prevent overlap. If custom CSS is applied, inspect it for conflicting properties like position, z-index, or margin, and adjust as needed. Also, verify the settings of the dynamic container or work area to ensure it adapts to the space below the header instead of using absolute positioning. Use browser developer tools to inspect the layout and identify overlapping elements or broken styles. If the issue persists, test the layout with a new harness to rule out configuration problems, or check for product defects in your Pega version you can reach Pega SR team on this as well. thanks
