Open Isoconfig.xml from <project folder>\Isometric\<the used iso style folder>, use therefore a good XML Editor like XML Notepad.
Switch to the node "Themes - Theme (name = Default) - Dimensions - DimensionTypes - DimensionType (name = String) - Anchor Points - Anchor Point (name = Flange).
Remove tag "ConnectionType".
Copy from another Anchor Point the "folder" "EndPoints" and paste it into this Anchor Point.

Save the file.
