My 2014 S did that once when I reprogrammed the eco (custom) and then shut the bike down before riding it as I normally do. When I turned it back on the following day, the display went berserk like that until I turned off the ignition and turned it back on again. I learned a lesson that time and ever since then when I reprogram the custom mode using the Zero app, I always go for a ride for a short distance and have never had that problem again. I think the bike takes a while to fully complete the reprogramming sequence.
Once last December I had a similar display, but this time the red warning light was on, too. So I unplugged the charger and plugged it back in and have never had that issue again. Looking in the owner's manual it appeared to be an indication that the on-board charger failed a self-test. My bike has had about 400 charges so far and that has only happened once. My garage was about 50 degrees F at the time, too.
