Terraform Configuration Files

We have been seeing intermittent CBR failures during TF destroy for the TIM modules for the CBR rules/zones.
It looks like that all the rules are not getting detroyed first before deletion starts for the zones and then it is throwing an error like this
The network zone 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' is referenced by one or more rules and cannot be deleted.

Please include all Terraform configurations required to reproduce the bug. Bug reports without a functional reproduction may be closed without investigation.
