qmodel_OW2-MRL_CMR-v0.1.json.txt

In the above model (renamed to .txt), if I rename the metric Unanswered Bugs-3 at MRL_Quality > Quality_Unanswered_Bugs_CMR to Unanswered Bugs-2, I get an error UNIQUE constraint failed: prosoul_metric.name

I think it is somehow because Unanswered Bugs-2 already exists somewhere in the model. But yet, it should be possible to have several metric with the same name in others attributes, isn't ?
