V12: Where is connection qualifier text?

[kepNCI]

In network deployment diagrams created before v12, I had servers and switches defined and displayed as nodes. Where appropriate I used a CommunicationPath between two nodes with the text of the qualifier for the source and target to denote the speed, such as "10 Mbps".
In v12, while the qualifier text does display on the diagram, I cannot find the text in the CommunicationPath properties dialog. Would have expected to see it under Role(s)/Detail/Qualifier for SOURCE or TARGET.

Appears in v12 one can now add multiple qualifiers to connection's source/target, thus, I assume t_connector.SourceQualifier and t_connector.DestQualifier may not be used in v12 except as legacy and that the qualifiers are now stored somewhere else. I guess I can accept this going forward and I see that if I add a new qualifier with the same or different text as the previous one, the display updates appropriately, HOWEVER, for some reason, EA will sometimes change the value of Role(s)/Advanced/Owner to True, causing a dot end point to be drawn on the connection. Not sure why it does it.
