What method are you using for switching relays? I noticed that I can remove the ones marked in red via Primal on Android, but not on desktop browser.  

 I'm using Amethyst mostly and occasionally Primal on Android, but not on desktop. I usually use Nostrudel on desktop, but that's not often. 

 just use my free relay that blocks spam and syncs to the major relays for you: relay.poster.place  

 Yours is on my small list. 🤙
