am i supposed to earn at least on my CDG-YUL and none on YUL-YQB when booked together ?

The miles indication is very far from reliable. If your CDG-YUL is on AF and YUL-YQB is AC coded, you will earn miles on the transatlantic segment (complete with the usual FB 'generosity by nature') but not on the YUL-YQB.
