Need help with Index Lifecycle Policy

I'm trying to create a Index Lifecycle Policy but it's not rolling over. I've got the policy created to rollover at a certain size and it's linked to my index. I setup the index name of dns-7.6.2-000001 and gave it an alias of dns-7.6.2. It did create the next index number dns-7.6.2-000002 but the original is still growing and nothing is going into the new -000002 index. Under the details of the -000001 index, the Current Action says complete. Any ideas why it's not rolling over?
