Help... New to Printing - 2 sides are messing up

So I received and built my Ender 3 Pro and set it all up this weekend. It came with 3 prints saved to the memory card (Dog, Cat, Pig). I have printed the Cat and Dog so far, and am noticing that the front left and back right are experiencing issues, but the front right and back left print extremely well. I re-leveled the bed between printing the Dog and Cat and this did not resolve the issues, also tried a different filament as well with no luck. Any help would be appreciated...Brandon
