MR 816X in Cubase 8

Hi…sorry this is a year later:) Stuff happened. Back again now and having trouble with the fact that when I solo a track it mutes not just the other tracks but also the MR816 Out 1 and 2 to my powered monitors. I can switch this mute off but it is pretty irritating. Is this a set-up error on my part? I can’t find anything.
