Followed DDSS self storage instructions from Docs, but doesn't move data to s3?

[jst]

Hi ,

I followed the instruction to setup self-storage   https://docs.splunk.com/Documentation/SplunkCloud/7.2.7/Admin/DataSelfStorage?ref=hk

I've confirmed Splunk created the test file in my s3 bucket.

But it does not move my index data to the s3 bucket. I don't see any files expect the test one

Expect to configure my index with "Self-storage" and select "storage location",  do I need to do something to trigger? 

Any suggestion is appreciated. Thanks.

My index setting:

Earliest Event ==> "10 months ago", latest Event ==> "a month ago" , status ==> "Enable"

Searchable time (days) => 7

Dynamic Data Storage => Self Storage,  Self storage location ==> <my s3 bucket>

I have a similar problem except only some of my Indexes don't show up in the S3
