Hello,  
If you copy a tree node (Layout components) containing a “_" in its name, renumbering remove last text after "_” char.  
How to reproduce:  
1- Create a new Station  
2- Create a new Component Group  
3- Rename it “Group\_Test\_Test”  
4-Copy and past it in root  
Its copy is renamed “Group\_Test”, should be " “Group\_Test\_Test\_1”  
If you paste it a second time, RS create a “Group\_Test\_2”.

I think that the method looking for last index fail with text and assume it is a one.  
It should test if last part is a numeric value, else add “\_”.
