Odometer reading in digital speedometer display?

Help! I feel like a buffoon because I cannot figure this out. 3+ weeks into a CPO Q3 ownership, and up until earlier this week, I quite easily selected the digital speedometer display and the overall odometer reading seemingly automatically displayed. Perfect! Exactly what I wanted. Now, however, I must have hit some button or another I don't know, but I cannot get the overall odometer reading to display when I'm in the digital speedometer display. I get trip odometer readings #1 and #2 , but for the life of me I cannot replicate what I had displaying the first 3 weeks. What am I missing?
