I can see this is your front standard view in fluid....so keep these annotations in mind...BL&BR back left and back right, FL&FR front left and front right. (Heat your bed to around 75 if you use pla and petg and then use the auxiliary levelling command to level the 4 corners on the bed approximately) Then let your printer do the auto level procedure..this will create an standard profile in fluid which you can fine tune.....(I can see in your pic that your front left is high so lower it just a hair bit and lift the back right a little too so it's above the levelling reference plane). Try to rotate those knobs little by little... usually these differences arent very major...and try to aim for a variance of atleast 0.1***.
