velocity channel does not come in correctly.

I would like to get your opinion on whether it is a bug or a different way of doing things.

I'm using TY to cache particles with simple separate motion in mesh instances and render them in Vray.　
The velocity channel is wrong when I render them in consecutive numbers. It's obviously odd.
However, when I put them out in F9, they seem to respond properly where the velocity has dropped.

Please let me know what this is and if you have any solutions.
I will update the TY forum with the scene.

I also tried this, this seems a bug.
the velocities get added each time.
Maybe not a Tyflow bug perse but could be also a Vray bug.

@tyson can you give a look?
