It’s a normal behaviour, only the preferred route is announced to other peers.
We have the same here:
bird> show route 192.175.48.0/24
192.175.48.0/24 via 185.1.89.16 on eth2 [bgp_as112 2018-08-18] * (100)
[AS112i]
via 185.1.89.12 on eth2 [bgp_quantic 2018-08-18] (100)
[AS112i]
via 185.1.89.13 on eth2 [bgp_grifon_budic 2018-08-18] (100)
[AS112i]
bird> show route export bgp_izzycom where net ~ [ 192.175.48.0/24 ]
192.175.48.0/24 via 185.1.89.16 on eth2 [bgp_as112 2018-08-18] * (100)
[AS112i]
I just displayed one route in my example, but it’s the same for the others.
