KVS tool searches CX website based on the straight redemption I believe, which explains why you saw one seat for J redemption but when you called CX they said it's not available for PEY->J upgrade.
Makes sense now. Last night when my flight was set to CS3, I was able to select 3 full J redemptions on asiamiles.com. I guess when the availability doesn't match the full redemption on asiamiles, only then I know it's another award besides straight up redemption.
