Native child Components of Native root component does not change their position in editor

I have custom Actor class in C++. You can look on it here.

It created root arrow component and couple of child actor components that spawned blueprint from the editor.

When i place my c++ actor (BP_GameFieldCpp based on it) on the scene it created child components correctly. But when i tried to change position of this actor only root arrow changes position but children on the root arrow component stand still.

How can i fix this and auto-change positions of child components based on root component.
