JOSM told me i've found a bug while editing a relation

[grossing]

While trying to upload a changeset with roundabout 580 objects i got a fail message that there is something wrong in relation 62.611.
I told JOSM to download all pieces of this relation and opend the relation editor. One way was marked as incomplete (it was deleted during my edit session but before i told JOSM to update all data). I told JOSM to zoom to this way an then i got "Sie sind auf enen Fehler in JOSM gestoßen".

(My english could be better, you could ask me also in german if you need more information)

Here are the datas created by JOSM:
