Octatrack arranger/partial patterns

Hi - sorry if this is a recurring question, but I was not able to find it here…

I’m trying something quite basic with the arranger, but it does not play back smoothly. I’m using 128 steps as master length.

Basically a pattern (lets call it A1) will be run 3/4 of completion (96 steps of 128 total) then I want to run the last 32 steps as a separate row in the arranger (to make use of different mutes and use it as a type of transition).

So I just try the basic math:
A01 off 000 len 096
A01 off 096 len 032

I also tried changing len/offset to 094 or 098 or other in between to see if I can mend the “jumping” issue, but no matter how I put it, the transition is not 100% smooth, there is a noticable delay. What gives?

Which OS on the Octatrack?

that was a bug, it is corrected on latest O.S.
