C13 - auto increment midi channel broken?

Create a new instrument track. Then add 7 new midi tracks below it. In C12 and earlier these would auto-increment starting channel 2 to channel 8 and set to the same midi destination.

Now there is a good looking new box with various options, which looks like you can set the start channel. Nice! But… not nice. It no longer auto increments, it just creates 7 new midi tracks with the exact same channel.

Am I doing something wrong?
