Flashforge Finder Horizontal AND vertical lines on one side

Hello, I have an issue with my new Flashforge Finder, all my prints has weird lines on the side of the object (Same on all prints) Hard to explain but the line starts vertical, goes up a bit and then turns horizontal. wil continue halfway around a cirkular print. Then it will be fine for some layers and then appear again. I`m really stuck on this. See pictures, may need to zoom a bit, hard to take good pictures.
