If you used MM to build up some charge. You should stop somewhere and restart the car so they show up as EV miles.
However, I do not recommend using MM for charging the battery, unless you plan to drive in some very mountainous areas. Using the gas engine to charge the battery is not as efficient as using it in REX mode.
