<p style=”text-align: center;”>Installed m7120 slx brakes with an xt rotor. Bled the brakes but can not get rid of the rub. Both calipers have adapters in them. Any help.</p>

A good bleed is an important step but do not forget the rotors… They all have some runout and require truing. I try to keep my rotors +/- .002″ so that the brakes can actually self adjust and lever will be full and solid feeling.
Spin the wheel and use a flashlight to view the space between the rotors and pads. You might likely see the runout as you do so. A large amount of runout will retract the pistons into the calipers and cause extra travel of both the piston/pad and the lever.

Ride them a few times before driving yourself nuts.
rotors and pads need to bed together.
