Fixed wing V-Tail not going to default positions - Stabilized mode - QGC | CUBE Orange| Px4 stack

Hi,
I have a configured my V-tail Fixed wing mini Talon on a CUBE Orange FC with Px4 stack using QGC platform.
While in manual mode everything works pretty well. But when I change to Stabilized mode, the Ailerons are positioned in-line with the control surfaces but the V-Tail ruddervators don’t go to default positions for a stabilized flight mode . My Air frame is XUAV mini Talon .

The log files are available on link ( updated on 15/11/2021 )

i am using a Herelink radio telemetry system
Can you give some suggestions here . This may be a general troubleshoot procedure.
