I currently use a diagramming system called "StarUML" in its version 2.8.1, however when copying an element (ctrl + c - ctrl + v) from one folder to another the element does not make a "clone" but rather it moves and leaves an icon that still remains in the previous project, since when it is modified it is also modified in the project and even if it is deleted it is also deleted from the original project.
Here I tried to copy the packet of casualties and modify it to high but seeing the package of losses looks something like this:
Any way to copy the documents without problem?
