Entity with names not despawning

its normal for entity with names to not despawn but I've used other stuff as well such as "wait 100 ticks" and then "execute command in the name of entity kill @s" and even used nbt number tag yet it wont die.I am making a spell circle and it will teleport to wherever you look but i don't want it to teleport to me when it's other's spell circle so i made it have a name but unfortunately after doing so it wont die or despawn.
