The ec2-Plugin label defaults to "EC2 (****) - Jenkins agent EC2 US west 2 (i-**********)" although a slave label was provided during configuration. This results in Role-Strategy plugin throwing an error message when rules are set on which user has access to which slave.

Error Message: 

pending—‘Jenkins’ doesn’t have label ‘nonprodslave’; ‘user2’ lacks permission to run on ‘EC2 (nonprodslave) - Jenkins agent EC2 US west 2 (i-***************)’)
