Timeseries with Kibana and number in the index name

I'm using Elasticsearch 2.3 and Kibana 4.5.

I'm generating data using as index and index pattern with MM-DD-YYYY. Similar to tenant1name-2016.05.09

Kibana is able to detect the index, but unable to discover any data.
When requesting the data directly to elasticsearch, there is recorded
information.

When I change the name to tenantaname-2016.05.09 it worked correctly. Is there any way to have a number in the index name and visualize it with Kibana?

I tested this with updating my topbeat index to be topb3at and everthing worked as expected.

What is the output from http://localhost:9200/_cat/indices?v

I've run it again and this time I didn't have any issue creating an index with a number.
I don't know why I had this issue the previous time.

Sorry for the inconvenience and thanks for the help
