Update Signal References not working when using Pick (Wire Number Tags)

[TCWestern]

I try to update a single Signal Reference using the Update Signal References tool in Edit Wires/Wire Numbers. Once in the tool I have both of the upper check boxes checked and I use the Pick button to pick the source/destination I want to update. The reference actually updates okay, but the wire number tag doesn't. I am sure the signal source and destination are set correctly. I end up having to exit AutoCAD Electrical and restart it. Once I restart and use the same procedure to update the reference, it works fine. Is there any way to avoid having to exit and restart? I don't want to do a Project Wide update, I've tried using just the Drawing Wide update and that doesn't work either.

I have attached a screen shot of the menus I use for what it's worth.

Thanks in advance for any help.
