to get frustrated with not knowing why you can mute some people on Facebook Messenger but not others?

Why does it give me the option of muting some people but not others? It has nothing to do with if you're friends or not on there.

Anyone experienced this? Another Google fail!

you used to be able to put people in groups and that transferred to messenger, I closed my messenger right down to about six people

somehow the settings have gone weird and you do not seem to be able to do this anymore,
