2016 mp3 CDR won't play through the folders?

I had a 2008 Prius, and my memory is that it would keep playing songs through all of the CDR folders, one folder to the next (as expected). But my 2016 Prius Two apparently will not. At end of one folder, it just starts over at the top of the same folder. I always have to advance manually to the next folder, which requires too much attention when driving. CD format is ISO 9660+Joliet. Possibly this is my user error, but I don't know how to change it to play though all of the folders?
