Why can't I hide certain posts on my feed??😡

I don't think it's right to have suggested group posts show up on our feed. No one else think it's insensitive to have posts from "pregnancy announcements", "Oct 19 babies", or anything related while someone is ttc (whether they are struggling with infertility or loss)? Although I'm happy for their journey, it still hurts during times I am struggling.

I'm assuming the suggested groups are random but I don't see the point of it.

And when I hit the 3 dots to "hide posts from the group" it never goes away! I've been trying to hide this same exact post for days now and it ALWAYS pops up when I go to my feed.

Is it a bug? Why are these even on my feed, especially the ones that sometimes sting☹️😔
