Altium Powerdby connector to 3DX On Cloud Platform using Variants is not producing proper 3DX Product Structure

Using Altium Powerdby connector to 3DX On Cloud Platform (latest one), using Variants in Altium - some components not fitted to a Altium Variant are yet shown in 3DX product structure after saving the Altium project to 3DX.
Altium shows proper product structure, and out of 5 removed components inside a Altium Variant (not fitted), only 4 are removed from 3DX product structure. What are we missing ?
