That took 9 hours? What is your printing speed, 20mm/s? I print at 80mm/s and feel like that would be a 3 hour print if that 17% infill is to be believed. Now if you did it at 90% infill maybe... highly modified Maker Select + here.
Same thing happened to me- I just bought a 2.71 used and updated. All the names were gone. But one more hard reset (where you hold down the 2 buttons while turning it on) and they came back up. I believe that step was given in the how-to post that was a mile long!
