Frequent aggresive wrong motion of quadrotor

[SwiftGust]

Hi, In the simulation, it is often observed that quadrotor model follows trajectory undesirable way that the vehicle flip towards wrong direction then return & starts to follow trajectory (See GIF below)

This easily can be observed especially when transitioning from stopped state(WAIT_TARGET) to executing new trajectory(EXEC_TRAJ) or rarely seen while following trajectory.

I'd like to know why and is this can easily be solved?

Thank you

P.S. Launch file & parameters are left untouched.
