De-transition happens super early - other times perfectly fine

Hi - I’ve had several test flights now where the de-transition sequence seems to be inconsistent. Below are screenshots of the sequences and the associated logs are linked below. Appreciate any help understanding what his happening here.

Plane 4.1.7

  1. Normal:
    (airbrake, pos1, pos2, all executed and timed well)

  2. Bad:
    (does VTOL short 400+m out, de-transitions super early and taxis as a quad for over a minute to the landing point)

  3. Worked but unusual:
    (does VTOL short but executed and timed pos1 and pos2 properly)

Thank you
