Trouble with collision layers

This might be a dumb question, but I’ve looked at other posts on the topic, but their suggestions haven’t worked for me. I am trying to make it so that the on area entered signal will not detect the wrong area. For example, I want the pickaxe to only detect the breakable block, and I want the sword to only detect the slime. I’ve set the collision layers accordingly, and I’ve checked to make sure that both areas aren’t somehow active simultaneously, but for some reason both signals still activate whenever either area enters them. Is there any way I can fix this? Any help is appreciated.
