Issue is resolved once I have added the below modparam in cfg.

modparam("lcr", "lcr_count", 10).

But the issue is not fixed for the below one:

[root@zeodialer ~]# kamcmd lcr.dump_rules
{
    lcr_id: 1
    rule_id: 1
    prefix: 91
    from_uri: 
    request_uri: 
    stopper: 1
}
{
    gw_index: 1
    priority: 1
    weight: 1
}
{
    lcr_id: 1
    rule_id: 4
    prefix: 00091
    from_uri: 
    request_uri: 
    stopper: 1
}
{
    gw_index: 1
    priority: 1
    weight: 1
}
5
2

Why these two numbers are 5 and 2 are displaying in the output? Did I need to change something?
