[Web Browser] : Display phantom data (data does not exists on server)

The table show 4 nods, that's ok.

You have two "unknown" labels, attached to those two nods that have double relations (probably wrong insert query doubled with unknown label).

Also, you query don't ask for specific label, so all labels are returned and rendered. But result return nods, not labels and that's what you see in table result.

Everything is fine, as far as I can see.
