The chosen route is not simply the first matching row.
Not just the first match
The broad core row matches, but it is not the chosen row because a longer matching prefix exists.
Compare prefix lengths
The broad row has prefix length 16; the winning row has prefix length 25.
Not the smallest network number
The default network is numerically small and also matches, but its prefix length is shortest.
Summary
Forwarding choice is longest matching prefix, not first row and not smallest network number.
