Metal washer/ring inside atomizer

[ckgjt]

I have ordered 3 times from Green House One. Each time I have gotten the 510 low resistance atomizers. THIS time when I recieved my atomizers, when I looked down into it, there is a silver metal ring at the base of the bridge. It looks kind of like a washer. Is this standard for low resistance atomizers now or am I supposed to remove it? They don't seem to produce as much vapor. Does anyone know what I'm talking about?

Should I ask Greenhouse One? I was hoping someone would know what I was talking about but I probably should send them an email.
