Cause

With the indexed property Connection point cross-section / diameter (all, depending on DT adoption) on a function, it is possible to specify a cross-section or diameter for each connection point.

In this case, the connection points of the targets (target functions) connected to a function have different cross-sections or diameters.

Solution

1. Enter the same value for the connection point cross-section or diameter on the targets (target functions).
2. Refresh the connections and then start a new check run.
