I got the same on the CentOS Linux release 7.2.1511 and Percona Server 5.7.12-5-log.
All the channels appears with the 1st's channel_name when use "show slave status", but it works normally for all commands with "FOR CHANNEL".
But you always have to remember the channel_name setted by command "CHANGE MASTER TO".
