Hello Theyurt, Welcome to the Sage ACT! Online Community!
If I understand your issue correctly (tabs pulled up too far), you should be able to resolve this by: - open layout in Layout Designer - look for small area above the tabs, single click on the line just above the tabs. It will be selected when you see the dotted line contain a small white square in the middle of it.
It will select the tabs area which can then be dragged down, exposing the detail section.
