No worries, it’s the normal shift pattern for the selected drive modes. I’ve only seen 2nd on mine once or twice in normal or eco mode, and it was when I let off the gas right at the top of the RPM range where the truck was about shift up. I can’t remember off the top of my head, but it also tends to skip another one - maybe 4th - under constant acceleration. Symptoms of normal operation 👍🏻
