Physics Asset Constraint settings missing from the interface.

Hi Dear UE Team:

We are doing some character physics asset work, and found out some useful settings are missing from the constraint setting interface.

On the online document: https://docs.unrealengine.com/latest/INT/Engine/Physics/Constraints/ConstraintsReference/index.html
There are “Angular Rotation Offset” settings.

But on our 4.18 editor interface:

Please, if there is a crucial reason for that, we would like to know, or if it is safe to show those settings.

Thanks a lot
