Thanks for following suggestion on creating new thread.
Its strange, how could your CUOBJ is 0000000000 and you have material variants created from that configurable materials?
I suggest again check all settings for variant configuration are update date for your configurable materials, give it a try to simulate your configurations using CU50.
Also check below link for document it will give you idea about various tables and relationship with each other for saving configuration, hope it will give you idea on VC setup.
Configuration information flow with an example mode
Thanks
