Transporter (Input port not shown in Properties/General/Ports)

1) The Transporter behaves as expected (it follows the network nodes). the problem is that developers have forgotten to add the A key connection (shown visually) to the input ports shown in Properties/General/Ports. Is it my platform (v.5) problem or ...?
:..:
better formulated:
It seems that for all the connections of network nodes (except those for other network nodes), the General tab of properties doesn't indicate the connections in the ports. if u look at the picture attached, there is no indicator for blue and red connections in Properties/General/Ports.

Works well in my System.
But there doesn´t happen anything if I press the "Properties" Button in this field!? Does this make sense?

When you associate a transporter or fixed resource to a network node with the 'A' key, you're not defining input ports, but 'travellers' and 'stations'. These are not currently displayed on the properties General tab. But they could be added as an enhancement.

The 'A' connections between network nodes are implemented as output connections only which is why you only see them in that part of the General>Ports listbox.
