yep... I wouldn't muted all the others.

Are all of the posts you are seeing quoting your muted post short?

I ask because it's not uncommon to see bigger posts with a muted post in the middle. I have seen users asking to see the bigger post, because they didn't block that author, and just hide the inner post.

Maybe we need a setting somewhere that muted override your follow preferences and mute everything else it touches.
