Deleted keys come back

Hello,

I'm using riak KV in 2 nodes cluster.
I inserted hundreds of key/value pair and deleted all keys in a bucket.
After above process, I can get some keys if I get list of keys in the
bucket.
Why those keys remain? How do I delete keys reliably?
If I increase number of nodes to 5 , I can delete all keys in the bucket as
same way as I did.
My bucket property is the following.

    "name": "BUCKET_A",
    "active": true,
