Get trouble with particle direction when changing offset options

Hello,

I met some troubles with particle direction when changing offset option from process during spawn to process during update. And particle went in a wrong direction.

Screen alignment has already been set to PSA Velocity.
What should I do to keep velocity along orbit direction with option set to process during update?

Everything works well in UE 4.7.
However, when I put the same system into UE 4.9, particles went in a wrong direction.
I did not find any change in release notes about this from 4.7 to 4.9. Am I missing something?

Thanks.
