Cause
The connection above and below the connection definition point branches at a T-node or a connection definition point is located on two crossing connections.
Solution
Possibility 1
Delete the target direction in accordance with the connection definition point before or after the T-node. Specify separate connection definition points for the branching connections.
Possibility 2
Move one of the connections from the intersection with the connection definition point.
Possibility 3
Move the connection definition point to one of the connections so that an intersection of both connections with the connection definition point is not possible anymore.
If required, start a new check run.
