You need the flattened refdes to be the same for all components which
are supposed to go in the same slot. (Ie. it won't work with
hierarchical naming.)

The fact that both elements in PCB get the first slot used does suggest
that the slot=2 attribute didn't take. You might try checking it is
correct in the schematic.
