You will always get retraction marks no matter what. Looks like you have your seem position set to Random. Try set it to Aligned or nearest. One or the other tends to chose a corner as the retraction point which makes it less visible and more hidden to a place where people may not look at if its something thats on display.
The current settings for retractions are:
Distance: 2.00 mm
Extra Distance: 0.00 mm
Vertical Lift: 0.00 mm
Speed: 30.00 mm/s

The starting position was set to optimize for fastest printing.
Should it be set manually?
If yes, then what would be a good location (x,0 / y,0) or center of build plate?
