    what does 'show route resolution unresolved detail' give?

    My guess:
    Issue of route recursion.
    for example:
    your route's next-hop is reachable by some kind of default route, the recusive next-hop is 172.16.0.14,
    but for 172.16.0.14 the next-hop route is "your route"--172.17.0.0/16, not the default route.

    this kind of route will be hidden.
