You can check what is actually advertised to the neighbor:
show route advertising-protocol bgp <neighbor-ip>

To understand why the prefix isn't advertised :
show route XXX detail

To advertise less-specific route when and only when you have more-specific
route:

[routing-options aggregate]
route xxxx/zz {
        policy <policy-name>;
        community [];
}

[policy-options policy-statement <policy-name>]
term accept {
    from protocol <YourIGP>; 
    then accept;
}
then reject;
