Configured Add-path path selection mode does not take effect

Setup details:
ODL (10.18.162.90) peering with XRv (10.18.133.131) and 2 ExaBGP instances (10.18.162.241, 10.18.162.231), all 3 configured as rr-clients

Add-path with all-paths scheme is enabled on ODL. Add-path is enabled on the 2 ExaBGP instances and they are configured to send prefix with different path-id’s

When sessions come up, prefixes with correct path-id’s show up in adj-rib-in and effective-rib-in of the peers. However the prefixes in adj-rib-out do not have path-id, and those in loc-rib have path-id 0. And ODL does not send the two paths it received from one ExaBGP peer to other ExaBGP peer but just sends one
