"Highway without ref" repeated x6 for each true positive

Each true positive match for the "highway without reference - Illegeal tag/value combinations" test is listed six times.
(Thus count of "highway without reference" is always a multiple of 6)
If I add a reference to one of the objects listed six times and revalidate, all the six "matches" is removed from the validator box.

Ticket was closed by me. It should not have been submitted in the first place, as I could not replicate the error after restarting JOSM.
