This an amazing bug, It fails to hold more than two rows because of this unique index:
CREATE UNIQUE INDEX /*i*/oresc_rev_predicted_model ON /*_*/ores_classification (oresc_rev, oresc_is_predicted, oresc_model);
when oresc_is_predicted = 1, it's useful because we should not have more than one predicated class per rev and model but when oresc_is_predicted = 0, it is too restrictive. I checked and to me, the whole index is useless so I completely drop it.

It's done now. \o/:
