Netcentric ACL tool same user group for separate environments

Hello, I'm using Netcentric AC tool for AEMaaCS environment, for our user-management. Ths issue is that I can't add the same group for example for stage and prod environment, as while testing it on local environment package insatllation gives following error

Exception while installing configurations: java.lang.IllegalArgumentException: Already defined authorizable: test-role-editor-EN found in configuration file: /apps/netcentric-stage/testing/test-role-editor-EN/config.yaml! This authorizable was already defined in another configuration file on the system!

So the configuration is defined under packages /apps/netcentric-stage/testing/test-role-editor-EN/config.yaml and /apps/netcentric-dev/testing/test-role-editor-EN/config.yaml
