When I try to copy a project from Administration/Projects, it displays all the items to be copied and their number correctly (Issues, versions, wiki, ...).

On the project I want to copy, there are two versions, one opened and one locked. Both have issues associated to them with the "Target version" field.

When I copy the project, the issues linked to the locked version are not copied.
Another problem is that it does not keep the hierarchy set with the "Subproject of" field.

Here are my installation details:
