A few things here…
If you have the original rotors, try assembling the new brakes and hardware and see if the rubbing still occurs.
If it does, the issue is either the new brakes shoes or the new hardware.
If there is no rubbing, the issue has to do with the replacement rotors.
Might also give a good visual inspect on the backing plate to see if it is bent.
You could also mark up the inside of the rotor with a large magic marker and spin the rotor and look for wear mark on both the rotor and assembled brake assembly.
