I tried to create a separate channel and instantiate separate chaincodes onto the channel. I was able to create separate channels but when I instantiate the chaincode onto the cahnnels, both the chaincodes are being instantiated on both the channels created.

Even though I have set the environment variable for CHANNEL_NAME: "channel2" and CHAINCODE_NAME: "arm2", both the chaincodes are instantiated on both channels.

Here is the yaml code for chaincode instantiation of instantiating chaincode "arm2" on the channel "channel2".

The image attached shows the chaincodes database which contains four rows consisting of chaincodes "arm1" and "arm2" on both channels "channel1" and "channel2".

How do I instantiate the chaincode "arm1" onto only channel "channel1" and chaincode "arm2" onto only channel "channel2"?
