Hi,
Yes, that seems pretty weird.
😮
Do you still have this issue? (if not, how was it solved?)
Have you tried completely uninstalling ARCHICAD and Rhino (and all their add-ons) and try again with a new and clean install of all?
It might also worth a try because other Rhino and Grasshopper Add-ons are known to cause issues with the add-on (so maybe another installed add-on causes the issue).
Also, see if it works with Rhino 5 (the Connection add-on is installed for the grasshopper add-on, so if you install it, it should work in both Rhino 5 and Rhino 6).
