Explorer shows content double

In the screenshot you may see double instances via classes details (right hand side in the screenshot). Although in the KG database only one record can be found. Hence, it is correctly represented with the visual circules to the left. But not on the right side.

I'm wondering where it's comming from.

Side info:

  • It does not matter if reasoner is on/off
  • I've done some modifications on the KG via "modeling". Not by adjusting the KG database file on the db or named graph itself.
  • PLC is subclass to asset and related (object property) to switches.

Kind Regards
