Delamination when the structure changes

Hi, i am fighting a bit with my SV07 Plus. Everything worked fine until now, when i noticed some layers do not stick well to each other. It happens always when there is a change in structure. For example where an overhang connects with a straight wall. I am using Orca, but it is also there with Cura. Any ideas? The marked line on the picture is the problem. The z direction is marked.
