Fx size problem after upgrading from 5.4.3 to 5.5.1


Unity 5.4.3f1 is used for my game, and I’m trying to upgrade to 5.5.1f1.
One problem is that the scale of one fx is not same.
size of spark effect is much bigger than older version.

Properties in inspectors are below and all properties are same between versions

Does anyone know what’s the problem??

Thanks in advance.

Answer by myself.

Updated to 5.5.1p2 solves the problem.

Releated issue is below.
