Bifrost: Making Duplicate of Motionfield does not work


Wanted to have many motionfields in Bifrost with same properties. Thought that simplying making a duplicate and then connecting it back to Bifrost would work but it does not.

The motionfields have boundary set.

The connection was made by selecting Bifrost and duplicated motionfield and then choosing Bifrost Fluids -> Motion Field

Anything wrong here?
