You have a resonant antenna with an SWR of 2:1 which is completely inconsequential at 40 and 20 meters. There is no functional reason to do anything to correct this; you will see no improvement in transmit or receive from doing so. I understand the intellectual and experimenter's challenge in achieving an SWR closer to 1:1 but your rig will work fine at that SWR and you achieve nothing other than satisfaction of doing it. Personally, I would spend my time and effort elsewhere where it might make a difference.
