When a container is copied, the elements it contains are duplicated

[mobdd]

Is the problem known? The current version is being used (3.1.0).

Hi @mobdd , this does not happen on my "Vanilla" Instance, and the are also Tests, for container copy, s. https://github.com/b13/container/blob/master/Tests/Functional/Datahandler/DefaultLanguage/ContainerTest.php#L194
Do you have more Information? Do you have other extensions installed?

Thanks @achimfritz for the reply.
Based on this statement, I will investigate the causes on the installation in question.
