Eigrp unequal cost LB question

I appear to be missing something here, but I'm not quite sure what it is - could someone kindly take a look?

I want R7 to adv two gateways for 150.1.5.5/32 in the RIB.  I've set variance to 2.  I've tweaked metrics and they so that the FS should now also be a S route:

R7#sh ip ei top 150.1.5.5/32
EIGRP-IPv4 Topology Entry for AS(100)/ID(150.1.7.7) for 150.1.5.5/32
  State is Passive, Query origin flag is 1, 1 Successor(s), FD is 131072
  Descriptor Blocks:
  155.1.37.3 (GigabitEthernet1.37), from 155.1.37.3, Send flag is 0x0
      Composite metric is (131072/130816), route is Internal
      Vector metric:
        Minimum bandwidth is 1000000 Kbit
        Total delay is 5020 microseconds
        Reliability is 255/255
        Load is 1/255
        Minimum MTU is 1400
        Hop count is 2
        Originating router is 150.1.5.5
  155.1.67.6 (GigabitEthernet1.67), from 155.1.67.6, Send flag is 0x0
      Composite metric is (131328/131072), route is Internal
      Vector metric:
        Minimum bandwidth is 1000000 Kbit
        Total delay is 5030 microseconds
        Reliability is 255/255
        Load is 1/255
        Minimum MTU is 1500
        Hop count is 3
        Originating router is 150.1.5.5

But the RIB only installs 1 entry:

R7#sh ip route | in 150.1.5.5
D        150.1.5.5 [90/131072] via 155.1.37.3, 00:21:42, GigabitEthernet1.37

Seems a bit basic but I cant see what else is required?
