When you have several robo ports clustered, as I do, when you place any logistic system components (chests, ports, etc), it sort of blinds you.
I speculate that there is an opacity layer stacked for each port to show coverage... I would suggest a calculation based on the currently ranged robo ports, and a maximum opacity, and make the overlay show as a percentage, that way it doesn't blind you to have good coverage.
Not a big bug, but still something that might be helpful to address.
