Issue in creating multiple peers in hyperledger ex

Question

I am trying to setup hyperledger explorer for my fabric network. I have 3 Orgs with one peer in each.

Network Config:-

     Organizations:
    - &StancOrg
        Name: StancOrgMSP
        ID: StancOrgMSP
        MSPDir: crypto-config/peerOrganizations/peerStanc.com/msp
        AnchorPeers:
            - Host: HOSTA.peerStanc.com
              Port: 7051

    - &StancOrgA
        Name: StancOrgAMSP
        ID: StancOrgAMSP
        MSPDir: crypto-config/peerOrganizations/peerStancA.com/msp
        AnchorPeers:
            - Host: HOSTA.peerStancA.com
              Port: 7051

    - &StancOrgB
        Name: StancOrgBMSP
        ID: StancOrgBMSP
        MSPDir: crypto-config/peerOrganizations/peerStancB.com/msp
        AnchorPeers:
            - Host: HOSTA.peerStancB.com
              Port: 7051

    - &OrdererOrg
        Name: StancOrderer
        ID: StancOrdererMSP
        MSPDir: crypto-config/ordererOrganizations/StancOrdr.com/msp

Based on it I have updated the explorer config file.

I have successfull hosted the explorer application.But its does n't show the list of 3 orgs as well as peers.It displays only the HOSTA.peerStanc.com as running.How can I list all the peers and their status as running ? I have updated the explorer config file in different ways.Can anyone help please? Help is appreciated.
