Changing netSlave's Symbolic Name does not modify project

Create a project with a netSlave DTM (OMB, PLS or any other netSlave).
Save the project, close it and open it.
Attached project can also be used to test this, just open it.

Right click a netSlave and select "Symbolic Name ...".

Modify the name and press OK button.

--> Project is not marked as modified.
When project is closed, there will be no notification to save the changes.
