Removing Thread Watch from Thread I no Longer have Access To Thread

Hi there,

Tried to search for a solution to this but couldn't find anything. I have a thread that I was watching before that was in a private group. I was removed from that group but I still have it in my thread watch list and am still receiving notifications when a new post is made in it. I can't see any way I can stop watching it. Does anyone know a way I can this removed at all?
