Does anybody else have a channels and stuff that they’ve unfollowed that will not go away?

It’s been a month or more now that I have actively unfollowed and subscribed and turned off all notifications for these channels. They are still coming up in my feed. I’m still getting notifications for stuff that has turned off. Is anybody else experience in this? My app is up-to-date and everything. My phone is up-to-date. Explain me why I can’t get rid of these channels. I don’t wanna see them anymore.
