Can not modify wire in LabVIEW 8.6 create with State Editor

Question

I have a VI created using LabVIEW 8.6 that incorporates a State Editor diagram (not State Chart).  After working on the VI for several weeks, I created a new State.  Some of the shift registers were pre-wired (first time I have seen this).  The wires connecting to the tunnels that connected to the shift-registers could not be modified.  Any clues on how enable modifications of these wires.

Answer 1

Blubell,
I have been able to recreate this with LV 8.6 and the SDE ( State Diagram Editor ) with the following:
1- Use the SDE to create a state diagram with several states. 
2 - Go the the block diagram and add a shift register to the outer while loop and wire through  case statement. 
3 - Right click the tunnel on the case statement and select 'Linked Input Tunnel>Create & Wire Unwired Cases'.  LV will go ahead and make the connections for you in the other case statements.  I guess its a new tool.  Unfortunately it is interacting with the SDE when you add another case and won't let you alter the connection for the new case.  It is locking this connection just like it locks several other things to the state diagram.
The cure appears to be this:
1 - Open the state diagram and delete the new case/cases. 
2 - Go to the block diagram and right click on the problem child tunnel and select 'Linked Input Tunnel>Clear'.  Now you should be able to go back to the SDE and add the new states.
