Indexes on Travel-sample not showing up in Index Tab during cluster-run

When we launch the couchbase cluster through ./cluster_run in ns_server, and add travel-sample and beer-sample buckets.
It shows in the side bar "Indexing travel-sample" after "Loading travel-sample".
After the loading is complete, the index tab is empty.

Also the following cbquery does not show any results:
cbq> select * from system:indexes;
{
"requestID": "fd340450-7297-492c-a686-ceff565f4402",
