@soerendomroes If the PortLabelPlacement.NEXT_TO_PORT_IF_POSSIBLE option is active, it produces this result for labels on ports that form a direct self loop. It looks like the layout either treats the ports as unconnected or connected through the node.

As a workaround, PR #1274 deactivates the option until the bug is fixed in ELK.
