the Mpg and MPGe stats disappeared from the Energy Usage Screen on my 2016 Chevy Volt

I was charging my car at a level 2 charger and when i was ready to leave I unpluged the charger and started up my car. I went to the enegy usage screen because i didn't think it was completely recharged and i noticed the Mpg and MPGe stats disappeared from the Energy Usage Screen on my 2016 Chevy Volt. They were there before it started charging. It was acting funny as i was parking too. the backup guide lines had disappeared from the backup camera and after turning the car off and on again the gridlines came back so i thought nothing of it. then all this with the energy usage screen, I could really use some help
