BGP routes being advertised by neighbour peer, relayed to local BGP peer,

Route shows up under received routes (with soft reconf ON) network 10.0.8.0/25 but is not being propagated into routers routing table

 

get router info bgp neighbors 172.16.0.9 received-routes VRF 0 BGP table version is 2, local router ID is 172.16.0.10 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal Origin codes: i - IGP, e - EGP, ? - incomplete     Network          Next Hop            Metric     LocPrf Weight RouteTag Path *> 0.0.0.0/0        172.16.0.9                             0        0 65535 3292 65108 44398 65168 ? <-/-> *> 10.0.0.0/25      172.16.0.10     0                      0        0 65535 i <-/-> *> 10.0.1.0/25      172.16.0.10                            0        0 65535 65500 ? <-/-> *> 10.0.2.0/25      172.16.0.10                            0        0 65535 65500 ? <-/-> *> 10.0.3.0/25      172.16.0.10                            0        0 65535 65500 ? <-/-> *> 10.0.8.0/25      172.16.0.9                             0        0 65535 3292 65400 65500 ? <-/->

 

but not in rib:

All other routes from BGP seems to be accepted, but not this one, i have similar issue with routes advertised in the opposite direction. All routing works via 0.0.0.0/0 but if i drop 0.0.0.0/0 via inbound routemap filtering then i cant route to 10.0.8.0/25.

Any ideas? i already talked to ISP (we have MPLS) and theyre blaming me.
