How Can Leader Listed As Replication (Slave) instead of Master

[Furkan KAMACI]

I use Solr 4.2.1 at SolrCloud. When I look at graph at cloud link of admin
page, I see that one of my node is listed as Leader. However when I
click core selector and clik my core there writes: Replication (Slave). It
is leader but a slave instead of being master. Do I miss anything? Can we
use Master-Slave terms for SolrCloud?
