Yes it looks like that. I never observed this, but I can think of the
following causes

(1) Maybe you have two configuration for the "Apache Stanbol Solr:
Managed Solr Server" that both use "default" as value for the
"org.apache.solr.core.CoreContainer.name" property. Two instances of
the service would cause the installation to happen two times. You can
check this in the Configuration tab of the Felix Webconsole
(2) The same could happen if you have two versions of the
commons.solr.managed Bundle installed. You can check this in the
Bundle Tab of the Webconsole
(3) Could there be two Stanbol instances running using the same
working directory?

If the above is not the reason for the issue you could check if both
indexes are active. Check for open Files in both directories and what
processes they are assigned to

That is caused by Stanbol during the deactivation of a SolrCore and
can be ignored.

Hope this helps in tracking down the reason for this behavior
