Per Track step length correct on first playback but repeats first page on second playback

Here is the setup:

All of my tracks are 64 steps except for MIDI A, which I want to be 48 steps.
I set the Per track step length for MIDI A to 48 steps, I press play, and on the first playthrough the pattern is correct. On the second playthrough, the first page repeats itself and then plays the second and third page, so it is still 64 steps but it is repeating the first page for some reason. What am I doign wrong?

Edit: Apparently I need to set the “M LENGTH” on the Page … page.

Looks like you figured out the Master length conflict :slight_smile:
