I can't see your "bitcoin-cli listtransactions"
However as the Payments page says on it "The payments below don't yet show when they have been sent."
The payments show up on the "Payments" page before they are sent.
I say in here when I have sent them.
They are sent after the block reaches +101
May I suggest you change the column title for "For block" instead of simply "Block", so that people easily differentiate "This payment is for block #999999" vs "This payment is included in block #999999".
