Bug Description
First, attached is the reference project test.zip.
Kicad shows a strange behavior when creating the connections (netlist) between eeschema and pcbnew. In the identical hierarchical drawings "LED" on sheet T2.sch is in each case a part of a multi-part IC (here 74AUC2G00).
Now the netlist visible in pcbnew:
In pcbnew only part B is connected. As an example, sheet Led0 and sheet5D88809D show the two related parts of U2. Port "P0" associated with sheet "LED0" is connected to part B of U2 used in sheet "sheet5D88809D" instead of part A to "Led0". The output of U2B is again connected to the component R3 from "Led 0". The connection "P3" has disappeared.
This behavior seems to be related to splitting a multi-part IC into multiple designs. (As a counterexample, see the wiring of U6 in sheet T2.)

In the first approach, I thought the behavior described above was stable.
The assignment of the connections changes according to rules that are not transparent.
In another test (see Test2.zip) I changed connection "P2" in the wiring of U6 in T2.sch to "P3": Now only the parts A in the sheets LED are wired.
