Update variant part based on latest configurable module not working

I am using Windchill PDMLink Release 13.0 and Datecode with CPS 13.0.0.4

Creating new variant part (steps followed):
1) Create configurable BOM (Parent BOM)
2) Create required option and choices
3) Create Option Set and map choices
4) Assign Option Set to a container
5) Create Product Family
6) Create Product Model
7) Create Managed Vairant Specification
😎 Assign Configurable Module to Product Family
9) Request Deliverables from above Variant Specification.
A new variant is created.

Update variant specification based on configurable module changes
1) Add few components to configurable module and check/in.
2) Use action Request Deliverables in Variant Specification, to propagate changes to Variant part.
This is not working, variant specification is still pointing to previous iteration of configurable module.

How to reflect changes in configurable module to variant spec and then to variant?

Here are the errors that I faced
