This > can be considered a bug in alsamixer. The current ALSA mixer abstraction splits the multi-channels into separate paired channels. But alsamixer can't show the channel name due to its UI design. And I guess other mixer apps don't handle them properly, too (who would care?). A solution would be make individual control like "Front", and create a virtual master control. JU a virtual control in the conf file or in the driver?
