There are going to be some lines because you have the bottom pattern set to "concentric". The lines will be where the nozzle shifts to the next loop.
That heavy line going from the middle area to the top looks more like there was an extrusion at the start when the nozzle traveled from the outer wall to start the concentric skin. If there was no retraction there then you didn't get a Z-hop either. Check your Travel settings for "Retraction Minimum Travel" and "Max Comb Distance with No Retract". For that print both should be low numbers like around 3 to 5.
You might also try "Avoid Printed Parts When Traveling" and see if it helps.
