Recently I just upgraded from Pega 7 to Pega 8.6. Unfortunately I found a portal that's overlapping with the header. The layout below is harness with screen layout header left. At first, I thought it caused by the layout content, but nothing happen when I make the layout content invisible. Then I tried to customize using inspect element, worked but when I put it on inline style it doesn't work.
@ChandanU5252 yes, there's custom css on the skin rule and I enlarge the min-height. Turns out it doesn't work that way, so I edit the image on the section header to fit the header area (I edit image height from 100px to 40px).
