I already have an import filter:

##################
#      OSPF      #
##################

protocol ospf ospf_ipv4 {
        ipv4 {
                import all;
                import keep filtered;
                import limit 200 action block;
                import filter {
                        accept;
                };

                export filter {
                        if (proto = "kernel1" || proto = "direct1") then accept;
                        else reject;
                };
        };

        area 0.0.0.0 {
                interface "enp3s0f1.33";
        };
}

protocol ospf v3 ospf_ipv6 {
        ipv6 {
                import all;
                import keep filtered;
                import limit 200 action block;
                import filter {
                        accept;
                };

                export filter {
                        if (proto = "kernel1" || proto = "direct1") then accept;
                        else reject;
                };
        };

        area 0.0.0.0 {
                interface "enp3s0f1.33";
        };
}


But if I use 'route count', I have reasonable values:
bird> show route count protocol ospf_ipv4
63 of 2461477 routes for 737544 networks in table master4
bird> show route count protocol ospf_ipv6
19 of 239272 routes for 63565 networks in table master6
bird> show route count export ospf_ipv4
9 of 2461477 routes for 737544 networks in table master4
bird> show route count export ospf_ipv6
10 of 239279 routes for 63564 networks in table master6
