Version 22.214.171.124 SQL Server Repository (2012).
User has an existing project with one Environment with 3 connections. User goes to create a new environment and it has 3 rows copied from the first one. (WCM-SIT is the first one) when he clicks on adding a new one one it defaults to the three connections and he can't remove any of them???
Release : 4.9
Component : CA Test Data Manager
Working as designed.
The new environment being created inherits the number of Data Sources from the previous environment.
To change this you would have to create a new environment in a new Project/Version.
