Billboard alignedAxis in 2D SceneMode head to wrong direction

I want to build a 2D flight tracker using Billboard with VelocityVectorProperty.

In 3D SceneMode, the Billboard can head to the right direction as same as the trajectory.

But in 2D SceneMode, the Billboard just head to the wrong direction in the first half of the time, while it head to the right direction in the latter half of the time. I pasted some screenshots below.

I want to know how to fix it, or you have a better solution.

Thanks a lot!!! :joy:
