How can I remove a channel from replication slave? Today my question is about MySQL replication cleanup.

I used mysqldump with the --master-info --all-databases tag and restored it to a new host to be used as a replication slave. 

After restore, I see some artifacts of slave information from the master. This is the third host in a replication chain.

I issued reset slave for channel 'xxxxx'; which returned Query OK, 0 rows affected (0.00 sec). When I later query using show slave status for channel 'xxxxx';, I still see information for this replication channel appearing. 

How can I cleanup this replication channel such that it never accidentally starts, as well as cleanup the output of show slave status \G to only show the intended replication channel?
reset slave all for channel '[name]'
