Unable to update the security groups of an Elastic Beanstalk environment via the AWS management console

After an update of the AWS management console for Elastic Beanstalk last week I'm unable to update the security groups of an Elastic Beanstalk environment via the AWS management console? I can select a security group but when I try to add another one the first selection is lost. The selected security groups aren't saved when I update the Elastic Beanstalk environment.
