Hello Eric
To confirm if it has worked, please see the Browser list to the left of the diagram. In the example below, I have different Options on the two Wires. I then set a Rule so that only the Wires to the Right of the Inline Connector are Combined. Using the Visulaize icon (as I assume you have done) and selecting from the Browser list the main Combined SIG3, the wiring is generated, same as yours. There are still two wires (because the Options are different) but these are in sub-signals.
Note that when there are no Options and the Signals are different, then your results will be one Signal with one Wire.
If the above does not match your results, please log and SR and include your sample data so that it may be examined by a Support Engineer.
Regards,
Pat
