fluentd not sending data to elasticsearch while using the same template name

[hichamuntitled]

I have the fllowing configuration file for fluentd that contains:

<match docker.env1.**>
  @type copy
  <store>
    @type elasticsearch
    host es-host
    port 9200
    index_name .kibana_env1
    logstash_dateformat %Y%m%d
    type_name forever
    time_key @timestamp
    resurrect_after 5
    flush_interval 1s
    template_name template1
    template_file /fluentd/etc/template.json
    template_overwrite true
  </store>
  <store>
    @type stdout
  </store>
</match>
<match docker.env2.**>
  @type copy
  <store>
    @type elasticsearch
    host es-host
    port 9200
    index_name .kibana_env2
    logstash_dateformat %Y%m%d
    type_name forever
    time_key @timestamp
    resurrect_after 5
    flush_interval 1s
    template_name template1
    template_file /fluentd/etc/template.json
    template_overwrite true
  </store>
  <store>
    @type stdout
  </store>
</match>

while using template_name template1 for both blocks, nothing seems to be sent to elasticsearch, but when I've changed them to different names:
template_name template1 for the first match and template_name template2 for the second match, it seems that it worked and fluentd sends data to elasticsearch.

I was wondering if this is a normal behavior or no?

Using Fluentd and ES plugin versions
fluentd:v0.12-debian
ES plugin1.9.5
ES version 5.5.1

I conldn't reproduce without docker environment.
Docker environment is needed to reproduce?

[hichamuntitled]

Yes docker environment is needed.

@hichamuntitled
Is the index being generated for both the blocks when template name is same?
Also can you set the log_level to debug or trace and check the logs?
What is the content of template.json?
