Some channels have started showing as hidden in the Manage Channels grid.
If I remove the hidden flag from them they still remain hidden.
If I remove the keyword "Hidden" from the channel they remain hidden.
As soon as I click on close on the Manage Channel screen, then OK on the options screen, they become hidden again.
What am I doing wrong? I've previously unhidden channels using either of the above methods and it's worked (with a little back and forth as sometimes it would need to be done a few times to hold) but this time it really has me scratching my head.
I'm currently running MC29
