Octaquad VTOL configuration using Arduplane in cube orange

Position bars (highlighted in green) does not show up for Motor 5~8 in servo output tab of mission planner.
However, position bar and PWM values are shown for AETR and Motor 1~4.

Cube orange with Standard board (Proficnc) is being used.
Arduplane firmware: 4.0.5
Mission planner firmware: 1.3.80

Parameter settings
Q_Enable = 1
Q_Frame_Class=4
Q_Frame_Type=1

Snapshot of servo tab is attached for better understanding.

Same settings were tried for Latest firmwares 4.3.4 & 4.3.5 and similar issue was faced

  1. What could be the reason for not showing position values of Motors 5~8 in servo tabs? Although the relevant motor outputs are selected through Q_Frame_Class parameter.
  2. Motor 5~8 are Aux outputs. Is there some other parameter to enable them?
  3. Any help will be appreciated.

Best regards
