No. But I filtered on 0.0.0.0/0, and there is only one such route
entry.
Re-tested on vanilla 2.0.7. Same issue there. Default route is not
marked with asterisk. Tested on different setups, all showing same
intermittent reporting of the primary route.
BIRD v2.0.7 ready.
bird> show route
Table master4:
0.0.0.0/0            unicast [kernel1 11:10:53.058] (215)

Hi
What is your config? It is possible that you have some 'keep filtered'
routes in net->routes for 0.0.0.0/0?
Configuration looks like this;

protocol kernel {
    learn;
    persist;
    scan time 120;
    ipv4 {
        import all;
        export where (source != RTS_DEVICE);
        preference 215;
    };
}

protocol kernel {
    learn;
    persist;
    scan time 120;
    ipv6 {
        import all;
        export where (source != RTS_DEVICE);
        preference 215;
    };
}

protocol device {
    scan time 60;
}

protocol direct {
    ipv4 {
        import all;
        preference 255;
    };
    ipv6 {
        import all;
        preference 255;
    };
    check link 1;
}
...
If there is only one route in list net->routes for 0.0.0.0/0 (as there
is no other in your output), then it should have asterisk.
Is it possible that due to some bug a temporary route added by kernel
during scan was not removed after the scan. Could you check the value
of X->attrs->source (and perhaps content of attrs->src) for X in
e, e->net->routes in this (or analogous) state:
...
...
(gdb) print e
$2 = (rte *) 0x56939d14
(gdb) print e->net->routes
$3 = (struct rte *) 0x56939c54
