Topology-UI shows LLDP links not correct

In the topology UI the LLDP links are shown twice for each direction. The information gathered by enhanced linkd are correct persisted in the database. The .PNG shows the real topology. The xlsx file is a dump with the link data. It seems the Topology UI visualizes a link in both directions which is a weird unexpected behavior.

The LLDP neighborhood data is not discovered correct. The correct topology verified with show lldp neighbor on the CLI is documented in cdp-test.png. The cdplink database dump in XLSX show the wrong detected links and interfaces. The comments explain what should be the correct value in the link entry.
