First I'd check if the model is good using X-ray, look for any red triangles. Something looks not right with the normals in that picture.
The other option is to make your cylinder solid, and then in the expert settings choose if you want a top or bottom as well, set fill % to 0, then pick your wall size. You can pick anything, down to .4mm.
You can cheat a little, and make your nozzle size 0.39 or smaller, untill it slices.
when I draw thin walls, I always make the walls 0.41mm thick.
