Sprite disappears in Scratch even when touching another sprite

Question

On my puppy salon project, I have run into a problem when I get to the necklace section. I want all the unused necklaces to disappear when they receive the message m11, but for the one on the puppy to remain. Right now, however, all the necklaces are disappearing.

This is the code that is run when the necklace is assigned to the puppy:

This message is received by each necklace:

My whole project is here.
