CouchDB does full replication instead of filtered replication?

I am having a source database name - profile-db. It has multiple documents...

Sample document

{
    "_id": "c24e1b6941dbaa8a1a1b76f233002038",
    "_rev": "4-d4edffe0da02900f3f1013baafc97757",
    "firstname": "Stacy",
    "lastname": "Edghill",
    "type": "female",
    "luckynumber": 9,
    "emp": 1
}

I have design document with filters within database - profile-db.

{
    "_id": "_design/rep_profile",
    "_rev": "3-4f56b9cb99cc818610508aa2f7b9cf36",
    "filters":{
        "rep_by_type": "function(doc, req) { if(doc.type== 'female') { return true; } else { return false; }}"
    }
}

I am using Futon for filtered replication. However, CouchDB is doing full replication instead of filtered replication?

Any pointers helping me to do filter replication would be great.

Thanks
