When I use soundcraftui: MUTE Groupls/ALL/FX: Mute with either my mute group "Mute All" or the MUTE ALL option I can toggle all mutes on and off.
When I use soundcraftui: Master channels: Mute to mute a channel I can use the same function to unmute it.
However, when I use soundcraftui: MUTE Groupls/ALL/FX: Mute to mute all channels, and then use soundcraftui: Master channels: Mute (with either the unmute or toggle option) to unmute one channel, that channel does not unmute.
This is different than if I perform these actions on the mixer itself.
