Cameo EA: Missing signals on IBD

[neal.london@lmco.com]

In Cameo Enterprise Architect (19): I committed changes to an IBD (after saving), and the signals on the connectors disappeared, except for a few of them. The signals and the item flows they are on are still in the model (I see them in the containment pane). I looked at the spec for the connectors, and the Conveyed Information has the signals. I figured it was some type of display toggle (Symbol Properties), but I could not find a way to 'turn on' display of the signals.I compared the Symbol Properties of the connectors without the signals displaying to the few connectors that still had the signals displayed, and there were no differences.
1) How can I 'turn on' display of the signals on the connectors?
2) If no way, is there a less painful way to get the signals on the connectors than re-dropping them on the connectors individually?
