I also have this kind of problem ，Maybe it's a aerodynamic problem，when the flap or Spoiler drop down at a large degree at low flight speed，and The FBW tends to use flap or spoiler to control Roll motion， That will cause wing stall。I solve this by stopping use FBW before landing or just let flap spoiler don't control Roll

yes，the entire line

You can try to open the CFG of that part，and delete “mirrorRefAxis = 0, 0, -1”
